Professional Applications & Engineering Value

Engineered for demanding industrial applications, these socket head cap screws deliver critical performance where reliability is non-negotiable. The 18-8 stainless steel composition provides excellent corrosion resistance in manufacturing environments exposed to moisture, chemicals, and temperature variations. The UNF fine thread configuration offers superior vibration resistance compared to coarse threads, making these fasteners ideal for precision machinery, automotive assemblies, and equipment subject to dynamic loads. With Class 3A thread fit ensuring tight tolerances and the 5/16" hex drive enabling high torque application without stripping, these screws solve common fastening challenges in maintenance, repair, and OEM operations where partial threading requirements exist for both clamping and alignment functions.

Specification Summary & Compliance

This socket head cap screw features precision 3/8"-24 UNF fine threads with Class 3A thread fit for superior dimensional accuracy and engagement. Manufacturing complies with ASME B18.3 specifications governing dimensional requirements and mechanical properties. Regulatory compliance includes RoHS 3 (2015/863/EU) restriction of hazardous substances and REACH (EC 1907/2006) chemical safety standards, ensuring environmental responsibility and workplace safety. The fastener maintains 70,000 psi tensile strength and Rockwell B70 hardness throughout its 2 1/4" length with partially threaded design.
