The featured fastener uses a square drive recess, providing positive engagement with the matching driver bit when adjustment or removal is required after installation.
Use the correct square-drive bit size for the selected fastener configuration. Drive dimensions can vary between nail-screw products, so the matching bit should be confirmed before installation.
Fine thread versions are available for suitable wood and panel applications requiring controlled thread engagement.
Coarse thread versions are available for suitable softwood and other compatible substrates where a more aggressive thread profile is preferred.
Thread selection should be matched to the substrate, penetration depth and required fastening performance rather than selected by material name alone.
These nail screws use 15° wire coil collation for sequential feeding through compatible pneumatic coil equipment. The featured .113" configuration contains 250 fasteners per coil.
Not every 15° coil nailer accepts nail screws. Tool compatibility should be checked using the complete specification, including collation type, diameter, length, head geometry, drive configuration and the tool manufacturer's approved fastener range.
Subfloor – suitable plywood and OSB fastening
Decking – compatible wood and panel applications
Sheathing – wall and roof panel fastening
Fencing – rails and pickets
Fiber cement board – suitable siding applications
Cabinet frames – furniture and woodworking assembly
