- Reduced wood splitting with partially threaded shank, allowing for precise clamping force and material integrity
- Secure, cam-out resistant installation featuring Phillips No. 2 drive for consistent torque application and reduced tool slippage
- Flush, professional finish with standard 82° flat head profile, ensuring smooth surfaces in wood assemblies
- Versatile material compatibility optimized for both hardwood (3/32" pilot) and softwood (5/64" pilot) applications
- Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe, industrial-grade use
Professional Applications & Engineering Value
These No. 8 wood screws deliver exceptional engineering value through their specialized thread forming design and Black-Oxide Steel construction. The partial threading prevents wood fiber displacement during installation, eliminating splitting in delicate hardwoods while maintaining maximum pull-out resistance. The flat head profile with 82° countersink angle ensures seamless flush mounting in furniture, cabinetry, and structural wood assemblies. With 15 threads per inch precision and right-hand thread direction, these screws provide rapid installation with superior thread engagement in both hardwood and softwood applications, making them ideal for high-volume woodworking operations requiring consistent performance and reduced assembly time.
Specification Summary & Compliance
Manufactured to precise inch system dimensions including 0.164" thread diameter and 2-1/2" length with standard Class 2A thread tolerances. Features include pointed tip for easy starting, partially threaded shank design, and compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
