• Environmental and regulatory safety with full compliance to RoHS 3 and REACH standards, ensuring safe use in global markets.

Professional Applications & Engineering Value

These No. 6 wood screws are engineered to address common challenges in woodworking and construction, such as material splitting and corrosion. The Black-Oxide coated steel provides a durable barrier against moisture, making them suitable for indoor and protected outdoor applications. With a thread forming design and partially threaded shank, the screws compress wood fibers rather than cutting them, significantly reducing the risk of cracks in hardwood and softwood. The Phillips flat head and 82° countersink enable seamless, flush mounting in furniture, cabinetry, and framing projects, ensuring a clean aesthetic while the right-hand thread with 18 TPI offers quick, reliable installation. This combination of features delivers consistent performance, reduces assembly time, and enhances the longevity of wood-based structures.

Specification Summary & Compliance

This product adheres to standard inch measurements with a thread diameter of 0.138" and approximately 18 threads per inch, ensuring precise fit. The flat head profile and Phillips drive are designed for common woodworking tools, supporting efficient installation. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) confirms the absence of hazardous substances, meeting international environmental and safety regulations for professional use.
