Professional Applications & Engineering Value
These No. 8 self-drilling wood screws are engineered to solve common fastening challenges in woodworking and construction. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making these flat head screws ideal for both interior and exterior applications where durability is critical. The integrated Type 17 drilling tip and thread-cutting serrations allow the screw to create its own pilot hole and tap threads simultaneously, drastically reducing installation time and preventing wood splitting. This is particularly valuable in high-volume assembly lines or on-site construction where efficiency is paramount. The square drive offers a more positive engagement than Phillips, minimizing tool slippage and damage to the screw head, which enhances worker safety and project quality.
Specification Summary & Compliance
This screw conforms to standard inch measurements with a No. 8 screw size, 1-1/4" length, and a 0.164" thread diameter with approximately 8 threads per inch. It features a right-hand thread and a partially threaded shank. The product is manufactured to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets strict environmental and safety standards for industrial use.
