Professional Applications & Engineering Value

These 316 stainless steel hex head wood screws deliver exceptional performance in demanding wood fastening applications where corrosion resistance and structural integrity are paramount. The thread forming design eliminates the need for tapped holes while creating compression-fit threads that significantly increase pull-out resistance compared to conventional wood screws. This makes them ideal for heavy-duty wood construction, marine environments, chemical processing facilities, and outdoor structures exposed to moisture and temperature variations. The external hex drive configuration allows for high-torque installation using standard tools, ensuring secure fastening in hardwoods, pressure-treated lumber, and composite wood materials. With their partial threading and precise 3/8"-7 thread profile, these screws provide controlled clamping force distribution while minimizing wood splitting, making them the preferred choice for professional woodworkers, industrial manufacturers, and construction professionals.

Specification Summary & Compliance

This 3/8"-7 x 1" wood screw features inch system measurements with a 0.375" thread diameter, 7 TPI thread pitch, and 1" overall length. Manufactured to ASME B18.2.1 specifications for dimensional accuracy and mechanical properties. The screw meets RoHS 3 (2015/863/EU) compliance for restricted hazardous substances and REACH (EC 1907/2006) compliance for chemical safety. The thread forming tapping method and right-hand thread direction ensure proper installation in wood applications, while the hex head configuration (0.563" width, 1/4" height) provides reliable drive engagement for industrial fastening requirements.
