• Versatile application compatibility with specific drill bit sizes provided for both hardwood and softwood installations

Professional Applications & Engineering Value

This 316 stainless steel wood screw addresses critical challenges in wood fastening applications where corrosion resistance and long-term structural integrity are paramount. The thread forming tapping method eliminates the need for separate tapping operations while creating stronger thread engagement in wood substrates. The Phillips flat head design with standard profile ensures clean, flush installations in furniture manufacturing, architectural woodwork, and outdoor construction projects. Engineered with 22 threads per inch and partial threading, this fastener provides exceptional pull-out resistance while minimizing wood splitting. The combination of right-hand threading and pointed tip facilitates straightforward installation in both hardwood and softwood applications, making it ideal for marine environments, chemical processing facilities, and outdoor structures where moisture and corrosive elements would compromise ordinary fasteners.

Specification Summary & Compliance
