Professional Applications & Engineering Value

These No. 12 wood screws are engineered to address common fastening challenges in wood and plastic-wood composite assemblies. The 18-8 stainless steel material provides excellent resistance to rust and weathering, making them suitable for outdoor furniture, decking, and structural joinery. The thread cutting tapping method (Type 17) ensures smooth penetration without pre-threading, reducing installation time and labor costs. Combined with the square drive system, these screws offer superior torque transfer, preventing stripping during high-stress applications. The partially threaded shank and flat head profile deliver strong clamping force while maintaining a clean aesthetic finish, ideal for both industrial manufacturing and custom woodworking projects.

Specification Summary & Compliance

This product features a No. 12 screw size with a 0.216" thread diameter and approximately 7 threads per inch in a right-hand thread direction. The partially threaded design ensures optimal grip in wood and composite materials. Manufactured to precise dimensional standards, these screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material reliability for professional use.
