• Reduced maintenance requirements due to exceptional durability and corrosion resistance properties

Professional Applications & Engineering Value

This 316 stainless steel hex head wood screw delivers exceptional engineering value in wood construction applications where corrosion resistance and long-term structural integrity are critical. The thread forming technology creates permanent, high-strength connections by displacing wood fibers rather than cutting them, eliminating the risk of loosening over time. The external hex drive provides superior torque transmission during installation, while the partial threading concentrates gripping power precisely where needed. These features make it ideal for demanding environments including marine construction, outdoor decking, and structural wood assemblies where exposure to moisture, chemicals, or temperature variations would compromise ordinary fasteners. The combination of premium 316 stainless steel material and precision manufacturing ensures reliable performance in the most challenging wood fastening applications.

Specification Summary & Compliance

This 5/8" x 2-1/2" hex head wood screw features precision threading with standard inch measurements, including a 0.625" thread diameter and 5 threads per inch configuration. The screw maintains dimensional accuracy per ASME B18.2.1 specifications for consistent performance and compatibility. Manufacturing compliance includes RoHS 3 (2015/863/EU) compliance for restricted substance control and REACH (EC 1907/2006) compliance for chemical safety regulations. The thread forming design and right-hand threading provide reliable fastening performance in wood applications, with a minimum thread length of 1.667" ensuring adequate engagement for structural connections.
