Professional Applications & Engineering Value

Engineered for demanding wood applications where corrosion resistance and structural integrity are paramount, these 316 stainless steel hex head wood screws deliver exceptional performance in marine construction, outdoor structures, and industrial wood assemblies. The thread forming design eliminates the need for pre-drilling in many applications while creating compression forces that significantly enhance pull-out resistance. The external hex drive system provides superior torque transmission for high-strength connections, while the partial threading configuration ensures optimal stress distribution along the fastener length. These screws maintain their mechanical properties in temperature-variable environments and resist pitting and crevice corrosion, making them ideal for heavy-duty wood fastening in challenging conditions where ordinary fasteners would fail prematurely.

Specification Summary & Compliance

This 3/8"-7 x 3-1/2" wood screw features precision right-hand threads with 7 threads per inch and a minimum thread length of 2.333". Manufactured to exacting ASME B18.2.1 standards for dimensional accuracy and mechanical properties. The product is fully RoHS 3 (2015/863/EU) compliant and meets REACH (EC 1907/2006) regulations for environmental safety and restricted substances. The 0.375" thread diameter and 0.563" hex head width ensure proper fitment and driving performance in industrial applications.
