A wire coil nail screw is a threaded fastener collated in a coil for pneumatic installation. It is driven rapidly using a compatible coil tool in a similar way to a collated nail, while its threaded shank and recessed head provide screw-like fastening characteristics.
Unlike a conventional screw installed entirely by rotary driving, the nail screw is initially driven pneumatically. Where the head contains an accessible Torx, Phillips or square recess, the installed fastener can subsequently be turned with the appropriate driver for adjustment or removal.
| Feature | Wire Coil Nail Screw | Conventional Coil Nail |
|---|---|---|
| Installation | Pneumatically driven from a compatible coil tool. | Pneumatically driven from a compatible coil nailer. |
| Shank | Fine or coarse screw-type thread. | Smooth, ring or conventional screw shank depending on nail type. |
| Drive Recess | Available with Torx, Phillips or square drive configurations. | Normally no screwdriver recess. |
| Adjustment / Removal | Can be adjusted or removed with the matching driver where the installed head remains accessible. | Normally removed by pulling or prying rather than unscrewing. |
| Drive | Available Configuration |
|---|---|
| T-15 Torx | Six-lobe recessed drive for subsequent adjustment or removal with a T-15 driver bit. |
| #2 Phillips | Cross-recess drive for use with a matching #2 Phillips bit after installation. |
| #2 Robertson / Square | Square recessed drive for use with the corresponding #2 square bit. |
| Thread Type | General Selection Consideration |
|---|---|
| Fine Thread | Provides closely spaced threads and is commonly used where adjustment, withdrawal resistance and controlled engagement are important. |
| Coarse Thread | Uses a more aggressive thread profile and may be selected for suitable timber substrates requiring strong mechanical engagement. |
Thread selection should be based on the actual substrate and connection. Do not assume that one thread pattern always provides greater performance in every wood species or assembly.

These values are listed as estimated averages for product comparison. Do not use them as structural design values unless the required test method, substrate, fastener configuration and project approval have been confirmed.
Bright carbon-steel nail screws have no protective zinc coating and are intended for dry or protected applications where additional corrosion resistance is not required.
Electro-galvanized nail screws use an electroplated zinc coating for additional corrosion protection compared with bright steel. Select this finish according to the actual moisture exposure and project specification.
Hot-dip galvanized configurations provide a different zinc-coating system for applications requiring increased corrosion protection. Confirm coating requirements when the fastener will be exposed to weather or preservative-treated timber.
Mechanical galvanizing applies zinc through a mechanical plating process. Confirm coating thickness and required corrosion performance when this finish is specified.
Stainless-steel nail screw configurations are available within this fastener category for applications requiring greater corrosion resistance. Confirm the exact grade, drive, thread, diameter and length before ordering.
Subflooring and flooring assemblies
Wood structural panel sheathing
Plywood bracing
Timber fencing
Decking applications where the selected fastener and coating meet project requirements
Timber and wood framing assemblies
Siding and exterior wood components where the specified finish is suitable
Cabinet and furniture frames
Pallet manufacturing
Wooden crates and industrial packaging
Threaded nail-screw fasteners are used in subfloor systems because they combine rapid pneumatic installation with threaded engagement in the supporting material.
For subfloor applications, select the fastener according to panel thickness, joist material, required penetration, thread profile and applicable construction specification. Specialized thread designs are available in the market for reducing panel movement, but performance depends on the complete fastening system.
Wire coil nail screws are also used in pallet and crate manufacturing where production users require rapid installation together with threaded engagement and the ability to remove selected fasteners using a driver.
Specify diameter, length, thread type and finish according to the timber species, joint design, required withdrawal resistance and service environment.
For suitable fencing and decking applications, the threaded shank can provide increased mechanical engagement compared with a comparable smooth-shank nail, while the recessed drive allows later adjustment or removal where accessible.
Exterior use requires a finish or material appropriate for the exposure conditions and timber treatment. Electro-galvanized, hot-dip galvanized, mechanical galvanized and stainless options should not be treated as equivalent.
The 15° collation angle alone does not establish tool compatibility. The nailer must also accept the .113-inch diameter, 2-1/4-inch length, wire-coil configuration, head profile and coil dimensions of the selected nail screw.
Some 15° coil nailers are designed only for smaller siding nails, while other framing, pallet and dedicated nail-screw tools accept larger .113-inch fasteners. Always check the manufacturer's approved diameter and length range before use.
| Compatibility Check | Required for This Fastener |
|---|---|
| Collation Angle | 15° |
| Collation Type | Wire Coil |
| Nominal Diameter | .113" / 2.87 mm |
| Fastener Length | 2-1/4" / 57.1 mm |
| Head Geometry | Must fit the tool's driver and feed system. |
| Coil Capacity | Tool magazine must accommodate the selected 250-piece coil configuration. |
Different 15° coil nailers are designed for different fastener classes. A siding nailer may accept smaller-diameter fasteners, while framing and pallet nailers can accept larger shank diameters. Dedicated nail-screw tools are also available for threaded wire-coil fasteners.
For this reason, provide the exact nailer manufacturer and model when requesting a quotation. KYA can then compare the required diameter, length, head, wire collation and magazine dimensions before bulk ordering.

Discuss Your Nail Screw Requirement
This model measures approximately 2.87 mm / .113 inch in diameter and 57.1 mm / 2-1/4 inches long.
The fasteners are supplied as a 15-degree wire-collated coil.
The current 2.87 mm product specification lists 250 fasteners per coil.
It is a nail-screw hybrid. It is collated and pneumatically installed like a coil nail but uses a threaded shank and recessed drive associated with screw-type fasteners.
Where the recessed drive remains accessible, the installed nail screw can be turned using the matching Torx, Phillips or square driver. Removal performance depends on thread design, substrate and installation depth.
The 2.87 mm product family lists T-15 Torx, #2 Phillips and #2 Robertson square drive options.
Fine and coarse threads use different pitch and engagement characteristics. Select the required thread according to wood species, substrate, required withdrawal performance and whether later adjustment or removal is important.
For the listed 2.87 mm x 57.1 mm configuration, KYA publishes approximately 1,218 lbs estimated average shear and 525 lbs estimated average withdrawal. These are reference test values, not universal design loads.
No. A 15° angle alone does not guarantee compatibility. The tool must also accept the .113-inch diameter, 2-1/4-inch length, wire-coil configuration, head geometry and coil dimensions.
Some Bostitch 15° coil platforms may accept the general fastener class, while others may not. Provide the exact Bostitch tool model so diameter, length, head and feed requirements can be checked before ordering.
Some Metabo HPT / Hitachi framing coil nailers accept 15° wire-collated .113-inch fasteners in this length range, but nail-screw head and feed geometry must still be confirmed for the exact tool model.
Compatibility depends on the SENCO model. Some SENCO 15° siding nailers are designed for smaller-diameter fasteners and are not suitable for .113-inch nail screws. Confirm the exact tool specification before use.
Yes. Dedicated pneumatic tools for 15° wire-coil nail screws are available in the market and are designed around the head, thread and feed geometry of nail-screw fasteners.
Yes, nail-screw systems are used for subfloor applications. Select the exact thread, length and coating according to panel thickness, supporting material and the required fastening specification.
Specialized threaded subfloor fastening systems can help limit movement between panels and framing, but a generic nail screw cannot guarantee a squeak-free floor. Panel installation, adhesive, framing condition and fastener pattern also affect performance.
Yes, for suitable timber fencing connections where the selected diameter, length, thread and finish meet the application requirements.
Wire coil nail screws are used in selected decking systems. The required fastener material, coating, thread, head design and corrosion resistance must match the deck material and service environment.
Electro-galvanized fasteners provide zinc protection but should not automatically be specified for demanding exterior, permanently wet, treated-lumber, marine or salt-air environments. Select the finish according to the actual exposure requirement.
Stainless-steel configurations are available within this fastener category. Confirm the exact stainless grade, length, diameter, drive and thread configuration required for the order.
Use them in structural applications only where the exact fastener configuration is supported by the applicable engineering specification, evaluation, test data or project approval. The reference shear and withdrawal figures on this page alone do not establish structural approval.
