What is the Points of a Nails?
Diamond-shaped points are typical on nails designed for general use and make the nails easier to drive.
Long diamond-shaped points help minimize splitting of the materials you're joining.
A blunt point makes a nail harder to drive but less likely to split the work piece.
Nails with round heads are often for general-purpose fastening and construction. A round head allows good contact with the hammer but creates a rougher finish than other types.
Flatheads are round and relatively large. They make driving the nail easier and reduce the risk of the work piece pulling through the head.
Checkered heads have a raised pattern, which helps prevent the hammer from slipping off the nail.
Countersink and cupped heads are small — often not much larger than the diameter of the shank — and drive below the surface of the work piece to make the nail less visible. Cupped heads allow you to easily fill the nail holes for a smooth finish.
Clipped heads are relatively small D-shaped heads designed for use in strip nailers. They allow the nails to be collated or joined closely together in a line.
Smooth shank is easy to drive but doesn't offer much resistance against pullout.Smooth shank nails are the most common and are often used for framing and general construction applications. They offer enough holding power for most everyday use.
Spiral shank or screw shank rotates the nail as you drive it, much like threads on a screw. The thread or flute on the shank makes the nail easier to drive and helps keep the nail in place. Spiral-shank nails are often designed for use with hardwoods and may cause splitting in softwoods. Nails with spiral shanks are also known as screw nails.A screw shank nail is generally used in hard woods to prevent the wood from splitting while the fastener is being driven. The fastener spins while being driven (like a screw) which creates a tight groove that makes the fastener less likely to back out.
Ring-shank nails or annular nails are often used with softwoods. Like a spiral shank, the rings lock with the wood fibers to provide good holding strength.Ring shank nails offer superior holding power over smooth shank nails because the wood fills in the crevasse of the rings and also provide friction to help prevent the nail from backing out over time. A ring shank nail is often used in softer types of wood where splitting is not an issue.
Annular thread shank is very similar to a ring shank except the rings are externally beveled which presses against the wood or sheet rock to prevent the fastener from backing out.
The nail material and finish help determine what projects you can use a nail on. Steel is the most common material, but it's vulnerable to corrosion. Steel nails that'll contact moisture or be used in pressure-treated wood need a corrosion-resistant coating or plating.
Bright nails are untreated steel, suitable for interior use.
Bright fasteners have no coating to protect the steel and are susceptible to corrosion if exposed to high humidity or water. They are not recommended for exterior use or in treated lumber, and only for interior applications where no corrosion protection is needed. Bright fasteners are often used for interior framing, trim and finish applications.
Black phosphate is a coating for indoor applications. It works well for drywall nails because the coating creates good adhesion with paint and drywall mud. Black phosphate gives nails a gray or black appearance.
Zinc-plated nails have some corrosion resistance, but standard zinc plating is thin and best for indoor applications. Zinc plating adds a silvery or gold tint.
Electro Galvanized fasteners have a very thin layer of Zinc that offers some corrosion protection. They are generally used in areas where minimal corrosion protection is needed such as bathrooms, kitchens and other areas that are susceptible to some water or humidity. Roofing nails are electro galvanized because they are generally replaced before the fastener begins to wear and are not exposed to harsh weather conditions if installed properly. Areas near the coasts where salt content in rain water is higher should consider a Hot Dip Galvanized or Stainless Steel fastener.
Hot-dipped galvanized nails work for outdoor use due to a thicker zinc coating. The finish adds a flat, gray color. Hot-dipped galvanized nails are suitable for pressure-treated lumber — which can corrode unprotected steel — but don't work well for some wood species such as cedar and redwood. The coating reacts with oils in the lumber and can cause staining.
Hot dip galvanized fasteners are coated with a layer of Zinc to help protect the steel from corroding. Although hot dip galvanized fasteners will corrode over time as the coating wears, they are generally good for the lifetime of the application. Hot dip galvanized fasteners are generally used for outdoor applications where the fastener is exposed to daily weather conditions such as rain and snow. Areas near the coasts where the salt content in rain water is much higher, should consider Stainless Steel fasteners as salt accelerates the deterioration of the galvanization and will accelerate corrosion.
Stainless Steel (SS)
Stainless steel nails offer the best corrosion protection available. The steel may oxidize or rust over time but it will never lose its strength from corrosion. Stainless Steel fasteners can be used for exterior or interior applications and generally come in 304 or 316 stainless steel.
Vinyl coating and coatings on fasteners for nailers make them easier to drive and act as adhesives to increase the holding strength.
Nail length may be indicated in inches or by the penny system, abbreviated with a D (16D nails). Originally an indication of how many English pennies it cost to purchase 100 nails of an individual size, now the penny system indicates nail length. Higher numbers mean longer length
The nail length you need for a project (particularly structural projects) may be specified by a building code. Without a definite requirement, a general guideline for a good nail length is three times the thickness of the top material you're fastening.
You'll usually see the diameter of the nail shank indicated by gauge. A smaller gauge indicates a shank with a larger diameter. Larger gauges indicate narrower shanks.
Nail size is called a "penny", e.g. "a 6-penny nail". And now penny size is simply denoted by the letter "d". The following
table is the length of each number.

Nails for nailers or nail guns are available in different types including common, framing, finish, siding and roofing. Nail gun nails are joined or collated into coils or strips and connected by wire, plastic, glue or paper. Degree measurements indicate the angle the nails are collated. Make sure you match the nailhead type, collation type and angle to your nailer.
