Different types of nails are designed for different materials, loads, tools and exposure conditions. Common nails and framing nails are used for structural wood construction, roofing nails secure shingles and roofing felt, siding nails fasten exterior cladding, finish and brad nails attach trim, while concrete nails are made for masonry and other hard substrates.
Choosing the right nail requires more than selecting a suitable length. Buyers and installers should also compare the nail diameter, head design, shank type, point, material, surface coating, collation angle and compatibility with the intended nail gun.
Quick answer: Use common or framing nails for structural lumber, roofing nails for shingles, siding nails for exterior cladding, flooring cleats for hardwood flooring, joist hanger nails for approved metal connectors, concrete nails for masonry, finish nails for heavy trim, brad nails for light trim and pin nails for delicate moulding or temporary positioning.
| Nail Type | Primary Uses | Main Characteristics |
|---|---|---|
| Common nails | General construction, framing and structural wood assemblies | Thick shank, large round head and strong lateral resistance |
| Framing nails | Wall framing, roof framing, trusses, fencing and sheathing | Usually collated in angled strips or coils for framing nailers |
| Box nails | Light construction, crates and thinner wood components | Thinner shank than a common nail, reducing the risk of splitting |
| Sinker nails | General framing and hand-driven construction | Checkered head and commonly a vinyl or cement-coated shank |
| Brad nails | Light trim, decorative moulding, panels and small woodworking parts | Thin 18-gauge fastener with a small head and minimal visible hole |
| Finish nails | Baseboards, window casing, door trim, cabinets and crown moulding | Stronger and thicker than brads, with a small head that can be concealed |
| Pin nails | Delicate trim, veneers, glazing beads and temporary positioning | Very thin, usually 21- or 23-gauge, with little or no visible head |
| Roofing nails | Asphalt shingles, roofing felt and selected roof coverings | Large head, short shank and corrosion-resistant finish |
| Siding nails | Wood siding, selected fiber cement products and exterior cladding | Corrosion-resistant material with a narrow head and strong withdrawal resistance |
| Flooring cleats | Tongue-and-groove hardwood flooring | L-shaped or T-shaped profile designed for flooring nailers |
| Concrete and masonry nails | Fastening wood or light components to concrete, brick or masonry | Hardened steel with a cut, grooved, fluted or heavy round shank |
| Joist hanger nails | Joist hangers, framing anchors and approved metal connectors | Full round head and specified length and diameter for connector load ratings |
| Drywall nails | Attaching gypsum board to wood framing | Large head, ringed shank and phosphate-coated surface |
| Duplex nails | Temporary bracing, concrete formwork and short-term structures | Double head allows the nail to be removed after temporary use |
| Coil nails | Pallets, roofing, siding, fencing, packaging and high-volume production | Large quantities of nails connected in a coil for rapid pneumatic fastening |
Every nail has a head, shank and point. Changes to these three components affect how the nail is driven, how securely it holds the material and whether it remains visible after installation.
Large round heads provide a broad bearing surface and help prevent the fastener from pulling through wood or roofing material. Small finish-nail heads can be countersunk and concealed, while headless pin nails are selected when appearance is more important than independent holding strength.
The shank provides much of the nail’s lateral and withdrawal resistance. A thicker shank can provide greater strength, while a thinner shank may reduce splitting in light wood components. Shank diameter must be checked carefully for structural framing and metal connector applications.
Diamond points are widely used for general construction. Blunt points can reduce splitting by crushing wood fibers instead of forcing them apart, while chisel and fluted points are used for specialized wood, flooring or masonry applications.
Common nails are heavy-duty construction nails with a thick shank and large round head. They are used for framing, structural wood assemblies, general carpentry and applications where strength is more important than the finished appearance.
Common nails are often identified by penny sizes such as 6d, 8d, 10d and 16d. However, structural specifications should state both the actual nail length and shank diameter because common, box and sinker nails with similar penny designations can have different dimensions.

Framing nails are used for building walls, roofs, trusses, subfloors, fences and other structural wood assemblies. They are commonly supplied as paper-collated, plastic-collated or wire-collated strips for pneumatic, cordless or gas-powered framing nailers.
Common framing nail lengths include 2 inches, 2-3/8 inches, 2-1/2 inches, 3 inches, 3-1/4 inches and 3-1/2 inches. The correct length and diameter depend on the connection, wood thickness, load requirement and local fastening schedule.
Framing nails can have smooth, ring or screw shanks. They are available with full round, offset round or clipped heads, depending on the nailer system and market requirements.

Box nails resemble common nails but have a thinner shank. The reduced diameter makes them less likely to split thin wood, making them useful for boxes, crates, light construction and selected nonstructural carpentry.
A box nail should not automatically replace a common nail in a structural connection. Even when both nails have the same length or penny designation, the thinner box-nail shank can provide lower lateral and withdrawal capacity.
Sinker nails are general construction nails with a relatively flat or checkered head that helps reduce hammer slippage. Many sinkers have a vinyl or cement coating that makes the nail easier to drive and can increase friction after installation.
Vinyl coating should not be confused with corrosion protection. Vinyl-coated sinkers are generally intended for dry interior applications unless the nail also has an appropriate corrosion-resistant metal or finish.
Brad nails are thin finishing fasteners commonly made from 18-gauge wire. Their narrow shank and small head leave a small hole, making them suitable for decorative trim, panel moulding, picture frames, thin boards and light woodworking components.
Brads reduce the risk of splitting delicate material, but they provide less holding strength than 15- or 16-gauge finish nails. Adhesive is often used together with brad nails when the assembly requires additional long-term support.

Finish nails are thicker and stronger than brad nails. Common sizes include 15-gauge and 16-gauge finish nails, which are used for baseboards, door casing, window trim, cabinets, stair components and crown moulding.
Their small heads can be driven slightly below the wood surface and covered with filler. A 15-gauge finish nail generally provides greater holding strength, while a 16-gauge nail creates a smaller hole and can be suitable for moderately sized trim.

Pin nails are very thin fasteners, commonly available in 21- and 23-gauge sizes. They have a minimal head or no conventional head, allowing them to enter delicate trim with almost no visible hole.
They are used for glazing beads, veneers, narrow moulding, cabinet details, craft work and temporary positioning while adhesive cures. Pin nails have limited independent holding strength and should not be used for structural connections.

Roofing nails have large heads that help hold asphalt shingles, roofing felt and selected roof membranes without pulling through the material. They are commonly supplied as loose nails or 15-degree wire-collated roofing coil nails.
Roofing nails may have smooth or ring shanks and are commonly galvanized or manufactured from corrosion-resistant material. Nail length must provide the penetration required by the roofing product manufacturer and applicable installation standard.

Siding nails are designed for exterior cladding such as wood siding and compatible fiber cement products. They typically have narrower heads than roofing nails so they remain less visible after installation.
Ring or screw shanks provide additional withdrawal resistance, while hot-dip galvanized or stainless steel construction helps protect the fastener from outdoor moisture. The siding manufacturer’s instructions should determine the nail material, head diameter, length and installation depth.

Flooring cleats are specialized L-shaped or T-shaped fasteners used to install tongue-and-groove hardwood flooring. They are driven at an angle through the flooring tongue using a manual, pneumatic or air-assisted flooring nailer.
Cleats allow controlled movement in natural wood flooring and can reduce tongue damage when matched correctly to the flooring species, board thickness and subfloor.

Concrete and masonry nails are hardened fasteners designed for attaching wood, furring strips, light fixtures or other approved components to concrete, brick, block and mortar. They may have cut, grooved, fluted or heavy round shanks.
Masonry hardness varies significantly. A pilot hole may be required, and brittle or high-strength concrete may need an approved anchor or power-driven fastening system rather than a conventional hand-driven concrete nail.

Joist hanger nails are designed for metal connectors such as joist hangers, framing anchors, hurricane ties and structural straps. They commonly have a full round head and a diameter selected to fill the connector hole correctly.
Do not use ordinary 2d nails, roofing nails, brad nails, drywall screws or unapproved general-purpose fasteners in a structural connector. Connector load ratings depend on the specified nail diameter, length, quantity, location and corrosion resistance.
Some connectors permit short 1-1/2-inch connector nails, while double-shear hangers and other connections may require longer nails that penetrate through the joist into the supporting member. Always follow the connector manufacturer’s fastening table.

Drywall nails are designed to fasten gypsum board to wood framing. They commonly have a large cupped head that supports the paper surface and a ringed shank that helps resist backing out.
Black phosphate coatings are frequently used for interior drywall fasteners because they work well with joint compound and paint. Drywall nails are not intended for exterior, structural framing or corrosion-exposed applications.
Duplex nails have two heads. The lower head stops against the material, while the upper head remains exposed so the nail can be pulled out easily.
These nails are used for temporary bracing, concrete forms, scaffolding, event structures and other assemblies that will later be dismantled. They should not be selected for permanent finished construction unless specifically required.
Coil nails are nails joined together with wire or plastic and wound into a coil. A coil can hold more fasteners than many conventional nail strips, reducing reload frequency in high-volume applications.
They are widely used for pallets, wooden packaging, roofing, siding, fencing, cable drums, furniture frames and industrial production. Coil nails are available with smooth, ring and screw shanks in bright, electro-galvanized, hot-dip galvanized and stainless steel finishes.

| Shank Type | Characteristics | Common Applications |
|---|---|---|
| Smooth shank | Drives quickly and provides economical general-purpose fastening | Framing, boxes, pallets and general construction |
| Ring shank | Raised rings increase resistance to withdrawal from wood | Roofing, siding, sheathing, pallets, fencing and subflooring |
| Screw shank | Twists into the material and creates strong resistance to backing out | Hardwood pallets, flooring, decking and demanding wood assemblies |
| Fluted or grooved shank | Ridges aid installation and anchorage in hard mineral substrates | Concrete, masonry and selected metal-to-masonry applications |
Bright nails are uncoated or minimally coated carbon steel fasteners intended mainly for dry interior construction. They should not be used where the nail will be exposed to rain, persistent humidity or corrosive treated lumber unless approved for that condition.
Electro-galvanized nails have a relatively thin zinc coating. They provide limited corrosion resistance and are commonly considered for protected environments or applications with occasional moisture.
Hot-dip galvanized nails have a heavier zinc coating and are widely used for outdoor construction, fencing, decking, siding and compatible treated lumber. The required coating class should be confirmed for the project and destination market.
Stainless steel nails are selected for coastal environments, high humidity, cedar, redwood, food-related equipment and other corrosive conditions. Type 304 and Type 316 stainless steel are common options, with Type 316 generally selected for more aggressive exposure.
In the United States, many loose construction nails are identified by the penny system, written as a number followed by “d.” The designation is useful for general identification, but the actual diameter can vary between common, box and sinker nails.
| Penny Size | Nominal Common Nail Length | Typical Uses |
|---|---|---|
| 2d | 1 inch | Small craft and light woodworking applications |
| 4d | 1-1/2 inches | Light trim and thin wood components |
| 6d | 2 inches | Selected sheathing, trim and light construction |
| 8d | 2-1/2 inches | Sheathing, blocking and selected framing connections |
| 10d | 3 inches | Framing, built-up members and general construction |
| 12d | 3-1/4 inches | Heavy framing and structural wood connections |
| 16d | 3-1/2 inches | Structural framing and heavy wood construction |
For structural work, specify the nail by both diameter and length, such as 0.148 inch × 3 inches, rather than relying only on a 10d description.
Nail guns are designed around a specific fastener system. Two nails with a similar length may still be incompatible if they have different diameters, head styles, collation materials or strip angles.
| Compatibility Factor | What to Check |
|---|---|
| Nail length | The minimum and maximum fastener length accepted by the tool magazine and driver. |
| Shank diameter | The diameter range specified by the nailer manufacturer. |
| Collation angle | Common framing systems include approximately 21, 28 and 30 to 34 degrees; coil nail systems are commonly around 15 degrees. |
| Collation material | Paper tape, plastic strip, wire weld, adhesive or plastic coil. |
| Nail head | Full round, offset round, clipped, T-head, DA-head, brad or headless pin. |
| Shank type | Smooth, ring, screw, fluted or another profile accepted by the tool and application. |
Never force an incompatible strip or coil into a nailer. Incorrect fasteners can cause feeding problems, nail jams, incomplete driving, damaged driver blades and unsafe operation.
Identify the materials: Determine whether you are fastening softwood, hardwood, plywood, siding, roofing, flooring, drywall, concrete or a metal connector.
Determine the load: Establish whether the connection is structural, nonstructural, decorative or temporary.
Choose the nail type: Match the fastener design to the intended application.
Confirm length and diameter: Follow the construction drawing, fastening schedule or product manufacturer’s instructions.
Select the shank: Use smooth, ring or screw shanks according to the required driving speed and withdrawal resistance.
Select corrosion protection: Consider moisture, chemicals, salt exposure, treated lumber and the compatibility of dissimilar metals.
Check the tool: Match the fastener dimensions, head, angle and collation to the nailer.
Verify applicable requirements: Follow the building code, engineer’s specification and connector or material manufacturer’s installation instructions.
Choosing a nail only by length and ignoring the shank diameter.
Treating common, box and sinker nails as interchangeable.
Using bright steel nails in exterior or moisture-exposed construction.
Assuming a vinyl coating provides rust protection.
Using roofing nails, drywall screws or general-purpose nails in structural metal connectors.
Using finish nails or brads for structural framing.
Loading the wrong collation angle or nail-head style into a nail gun.
Replacing specified nails with screws without an approved substitution.
Nails are driven quickly and generally perform well in framing applications where the connection experiences lateral or shear forces. Screws provide threads that resist withdrawal and make removal easier, which can be useful for decking, cabinetry and assemblies requiring adjustment.
One fastener should not automatically replace the other. Structural connections must use the nail, screw or approved alternative identified in the design, building code or hardware manufacturer’s load table.

Request a Nail QuoteThe most common construction nail types include common nails, framing nails, box nails, sinker nails, roofing nails, siding nails, concrete nails, joist hanger nails, finish nails, brad nails and flooring nails.
Common nails and collated framing nails are used for wall, roof and floor framing. The required length and diameter depend on the lumber connection and fastening schedule. Common sizes include 8d, 10d and 16d nails and 3-inch to 3-1/2-inch collated framing nails.
A traditional 8d common nail is approximately 2-1/2 inches long. A traditional 6d common nail is approximately 2 inches long. Actual dimensions should always be checked on the product packaging or technical specification.
Common nails have thicker shanks and are used where structural strength is important. Box nails have thinner shanks that reduce wood splitting but generally provide lower capacity. They should not be substituted in a structural connection without approval.
Brad nails are commonly 18-gauge and are used for light or delicate trim. Finish nails are commonly 15- or 16-gauge and provide greater holding strength for baseboards, window casing, door trim and heavier moulding.
Pin nails are used for veneers, glazing beads, narrow decorative trim, cabinet details and temporary positioning while adhesive cures. Their extremely small diameter produces a nearly invisible fastening point.
No. Roofing nails generally have a larger head that holds shingles and roofing felt. Siding nails usually have a narrower head and longer shank for fastening exterior cladding. The two types should not be interchanged unless the material manufacturer permits it.
Only nails approved for the specific joist hanger should be used. The connector manufacturer specifies the required nail length, diameter, quantity and position. Ordinary short nails, roofing nails and drywall fasteners can reduce the connection’s rated capacity.
Hot-dip galvanized or stainless steel nails are commonly selected for outdoor use. The correct material depends on moisture, salt exposure, treated lumber, wood species and the required service life.
Vinyl coating primarily improves driving and holding performance. It should not be treated as a substitute for galvanization or stainless steel when corrosion resistance is required.
Ring shank nails generally provide greater resistance to withdrawal because the rings engage the wood fibers. Smooth shank nails are easier and faster to drive and remain suitable for many general framing applications.
Screw shank nails are commonly used in hardwood pallets, flooring, decking and assemblies exposed to movement or vibration. The helical shank rotates into the wood and helps resist backing out.
L-shaped or T-shaped flooring cleats and compatible flooring staples are commonly used for tongue-and-groove hardwood flooring. The flooring manufacturer should specify the correct fastener type, gauge, length and spacing.
No. Concrete hardness, age and aggregate composition affect nail penetration. Hard, brittle or structural concrete may require predrilling, an approved anchor or a specialized concrete fastening system.
Coil nails are used for high-volume applications such as pallets, wooden packaging, roofing, siding, fencing and industrial assembly. Their coil format provides greater magazine capacity and reduces tool reloading.
No. A nail must match the tool’s accepted length, diameter, head, collation material and angle. Using an incompatible nail can cause jams, misfeeds, incomplete driving or tool damage.
Only an approved structural screw should replace a specified nail, and the substitution must be permitted by the engineer, code, connector manufacturer or published fastening table. General-purpose and drywall screws are not automatic replacements for structural nails.
Provide the nail type, length, shank diameter, head style, point, shank profile, material, coating, collation type, nailer model, packaging, estimated quantity and application. Drawings, samples or existing product specifications can help confirm compatibility.
