• Reduced wood splitting risk with partially threaded design, minimizing damage to plywood and oriented strand board (OSB).
• Versatile drive compatibility with dual Phillips/Square drive options, allowing for flexible tool use and reduced cam-out during installation.
• Optimized for efficient installation featuring a standard 90° countersink angle and pointed tip for quick, flush seating in wood applications.
• Reliable dimensional accuracy with a thread diameter of 0.164" and 15 threads per inch, ensuring consistent fit and performance.
• Environmentally safe compliance meeting RoHS 3 standards, supporting sustainable procurement and usage in industrial projects.

Professional Applications & Engineering Value

These No. 8 wood screws are engineered to address common challenges in wood construction, such as material splitting and weak fastening in plywood and oriented strand board (OSB). Made from zinc-plated steel, they offer excellent durability against moisture and wear, while the thread forming method ensures tight, reliable threads that enhance pull-out resistance. The partially threaded shank design distributes stress evenly, reducing the risk of cracks in delicate wood substrates. With a flat head profile and dual Phillips/Square drive, these screws provide seamless installation and removal, making them ideal for furniture assembly, cabinetry, and structural woodworking where precision and strength are critical.

Specification Summary & Compliance
