Professional Applications & Engineering Value
Engineered for demanding industrial applications, these 316 stainless steel socket head cap screws deliver exceptional performance in corrosive environments where ordinary fasteners fail. The Class 3A thread fit provides precise tolerance control critical for machinery, automotive, and marine applications requiring vibration resistance. The passivated finish enhances the natural corrosion resistance of 316 stainless steel, making these hex drive socket screws ideal for chemical processing, food equipment, and offshore installations. With 70,000 psi tensile strength and Rockwell B70 hardness, they maintain structural integrity under heavy loads while the partially threaded design offers superior clamping force in precision assemblies.
Specification Summary & Compliance
This 1/4"-20 UNC socket head cap screw features Class 3A thread fit per ASME B1.1 standards with coarse thread spacing and right-hand thread direction. The fastener measures 1 7/8" in length with 1" minimum thread length, 3/8" head diameter, and standard socket head profile. Manufactured from 316 stainless steel with passivated finish, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
