- Full regulatory compliance with ASME B18.2.1, RoHS 3, and REACH ensures material safety and international acceptance
Professional Applications & Engineering Value
This 316 stainless steel hex head screw delivers exceptional engineering value where corrosion resistance and mechanical reliability are paramount. The combination of UNF fine threading and partial threading design addresses common industrial challenges by providing superior vibration resistance in machinery while allowing precise tension control in structural applications. With 70,000 psi tensile strength and Rockwell B70 hardness, these fasteners maintain integrity in high-stress environments from marine equipment to chemical processing systems. The external hex drive ensures straightforward installation in confined spaces, while the Class 2A thread fit guarantees consistent performance across production runs. These industrial screws are engineered to withstand aggressive environments where ordinary fasteners would rapidly deteriorate.
Specification Summary & Compliance
This 5/16"-24 UNF hex head screw features precise Class 2A thread fit tolerances with 2-1/2" length and 7/8" minimum thread length. Manufactured to ASME B18.2.1 specifications with right-hand threading and external hex drive. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for environmental safety and material restrictions.
