Professional Applications & Engineering Value

These 18-8 stainless steel wood screws are specifically engineered to address common fastening challenges in plywood and oriented strand board applications. The thread forming design creates permanent, high-strength threads without removing material, significantly improving pull-out resistance in composite wood products. The flat head profile with standard configuration ensures seamless countersinking, eliminating protrusions that could compromise surface integrity. The dual Phillips/Square drive system provides installation flexibility for various tooling setups while reducing driver slippage and workpiece damage. With partial threading maintaining full shank diameter along most of the length, these screws deliver exceptional shear strength while minimizing the risk of wood splitting in delicate applications.

Specification Summary & Compliance

This No. 9 size screw features a 1-1/2" length with 14 threads per inch and standard inch system measurements. The thread forming tapping method ensures consistent performance in wood substrates, while the pointed tip facilitates easy starting. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and industrial compliance. The screw's dimensional specifications include 0.177" thread diameter, 0.346" head diameter, and 3/4" minimum thread length for reliable fastening performance.
