Professional Applications & Engineering Value
These No. 8 wood screws are precision-engineered with zinc-plated steel and thread-forming technology to address common challenges in wood construction. The fully threaded design and right-hand threads ensure maximum holding power in plywood and OSB applications, preventing material splitting and providing exceptional pull-out resistance. The dual Phillips/Square drive allows for high-torque installation without cam-out, reducing tool slippage and improving efficiency. Combined with the flat head that sits flush upon installation, these screws deliver reliable, professional-grade fastening solutions for cabinetry, structural wood assemblies, and other demanding projects where durability and precision are critical.
Specification Summary & Compliance
These screws feature a No. 8 size with 1-3/4" length and 15 threads per inch, designed with standard inch measurements. The thread-forming tapping method and fully threaded shank ensure consistent performance. Installation is guided by a 5/64" drill bit and 90° countersink angle for proper fit. Compliance with RoHS 3 (2015/863/EU) confirms adherence to environmental safety regulations, making these screws suitable for professional and regulated applications.
