Professional Applications & Engineering Value

These zinc-plated steel wood screws deliver exceptional engineering value through their specialized thread-forming technology that creates stronger mating threads in wood substrates without pre-tapping. The Phillips/Square combo drive system addresses common installation frustrations by providing dual-drive compatibility, reducing cam-out incidents and improving torque transmission during high-volume assembly operations. Engineered specifically for plywood and oriented strand board (OSB) applications, the fully threaded design and pointed tip ensure rapid penetration and maximum thread engagement, preventing material splitting while delivering superior pull-out resistance. The flat head profile with 90° countersink allows for flush mounting in cabinetry, furniture manufacturing, and construction applications where surface aesthetics matter. This combination of features makes these screws ideal for professional woodworking, structural assembly, and manufacturing environments requiring reliable, high-performance fastening solutions.

Specification Summary & Compliance

These wood screws feature precision No. 6 diameter (0.138") with 18 TPI thread pitch and are manufactured to standard inch system tolerances for consistent performance. The thread-forming tapping method creates secure mating threads in wood materials without requiring pre-drilled threads. Compliance with RoHS 3 (2015/863/EU) regulations ensures environmental safety and regulatory adherence for industrial and commercial applications. The combination drive system accommodates both Phillips (#1/#2) and square drive bits, providing installation flexibility across various tool systems.
