Professional Applications & Engineering Value

This 18-8 stainless steel socket head cap screw with integrated split lock washer addresses critical vibration-induced loosening in industrial machinery, automotive assemblies, and precision equipment. The combination of Class 3A UNC coarse threads and fully threaded design ensures rapid installation and maximum thread engagement in tapped holes, while the hex socket drive provides superior torque transmission in space-constrained applications. Engineered with 70,000 psi tensile strength and Rockwell B70 hardness, this fastener maintains structural integrity under heavy loads and repetitive stress cycles. The 18-8 stainless steel construction delivers excellent corrosion resistance for outdoor equipment, marine components, and chemical processing installations where environmental factors compromise fastener performance.

Specification Summary & Compliance

Manufactured to ASTM F837 specifications with precision Class 3A thread fit and UNC coarse thread spacing. The fastener features 6-32 thread size, 3/4" length, and right-hand thread direction with standard socket head profile. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for environmental safety. The integrated split lock washer (0.204" OD, 0.04" thickness) is manufactured from matching 18-8 stainless steel for consistent performance.
