Professional Applications & Engineering Value
This 316 stainless steel socket head cap screw delivers exceptional engineering value in demanding applications where corrosion resistance and mechanical strength are critical. The UNC coarse threading with Class 2A fit provides reliable fastening in vibration-prone equipment, while the ultra-low head profile enables flush mounting in space-constrained assemblies. With its 70,000 psi tensile strength and Rockwell B70 hardness, this fastener maintains structural integrity in machinery, marine hardware, and chemical processing equipment where exposure to corrosive elements would compromise ordinary fasteners. The 5/64" hex drive ensures positive tool engagement, reducing installation time and preventing damage to the socket head during high-torque applications.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit tolerance and head diameter tolerance of -0.005" to 0.005". Features 8-32 UNC coarse threading with right-hand direction and fully threaded design. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial markets and restricted substance requirements.
