Professional Applications & Engineering Value
This 316 stainless steel socket head cap screw delivers critical performance advantages where corrosion resistance and mechanical reliability are paramount. The low profile head design combined with UNC coarse threading addresses common installation challenges in confined spaces while maintaining high clamp load capacity. Engineered with Class 3A thread fit precision, these fasteners prevent loosening under vibration in machinery, marine equipment, and chemical processing applications. The 70,000 psi tensile strength and Rockwell B70 hardness ensure dimensional stability under load, making these socket head cap screws ideal for structural assemblies requiring repeated disassembly without thread degradation.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 3A thread fit tolerance and UNC coarse thread form. The fastener meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements. Features include right-hand threading, fully threaded 1/2" length, 1/8" hex drive size, and consistent mechanical properties verified through hardness testing.
