Professional Applications & Engineering Value
This 316 stainless steel hex head screw delivers exceptional performance in demanding industrial applications where corrosion resistance and mechanical strength are critical. The combination of 70,000 psi tensile strength and Rockwell B70 hardness ensures reliable fastening in structural assemblies, machinery, and equipment subjected to continuous stress. The UNC coarse thread with Class 2A fit provides excellent engagement in both metals and plastics, while the fully threaded design maximizes clamping force distribution. Particularly valuable in chemical processing, marine, and food industry applications, this industrial-grade fastener maintains integrity in corrosive environments where ordinary fasteners would fail, reducing maintenance frequency and extending equipment service life.
Specification Summary & Compliance
This 5/16"-18 UNC hex head screw features precise Class 2A thread fit tolerances and coarse thread spacing per unified thread standards. Manufactured to meet ASME B18.2.1 specifications for dimensional accuracy and mechanical properties. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance compliance. The 4" length and external hex drive provide standardized installation compatibility across industrial applications.
