- Simplified installation process with compatible 1/8" drill bit size for precise pilot hole preparation
- Versatile material compatibility for both natural wood and plastic-wood composite applications
Professional Applications & Engineering Value
These No. 8 wood screws with corrosion-resistant coated steel construction address critical challenges in woodworking and construction applications. The T-15 Torx drive system eliminates the common problem of tool slippage and stripped drive heads, ensuring consistent installation torque in demanding production environments. The Type 17 thread cutting design with pointed tip reduces the need for extensive pre-drilling while minimizing material stress in both solid wood and plastic-wood composites. The partial threading configuration provides optimal clamping force distribution, preventing joint failure in structural applications where vibration resistance is essential. These engineering features combine to deliver reliable, long-term fastening solutions for decking, furniture assembly, and architectural woodworking projects.
Specification Summary & Compliance
Manufactured to precise inch system specifications with 0.164" thread diameter and 10 threads per inch for consistent performance. Features Type 17 tapping screw geometry with right-hand threading and partial threading up to 2.42" minimum thread length. The flat head profile with narrow design ensures flush mounting in various wood materials. Compatible with standard 1/8" drill bits for pilot hole preparation. These screws meet industry standards for wood screw applications and are manufactured using corrosion-resistant coated steel for enhanced durability in challenging environments.
