Professional Applications & Engineering Value

Engineered for demanding industrial environments, these socket head cap screws leverage A286 stainless steel's unique properties to solve critical fastening challenges. The passivated finish creates a protective oxide layer that significantly enhances corrosion resistance in chemical processing, marine, and aerospace applications where exposure to harsh elements is common. The UNRC coarse thread design combined with Class 3A fit provides superior vibration resistance, preventing loosening in dynamic machinery and equipment. With 160,000 psi tensile strength, these fasteners maintain clamping force under extreme thermal cycling and mechanical stress, making them ideal for high-performance assemblies requiring reliable, long-term fastening solutions where failure is not an option.

Specification Summary & Compliance

This 8-32 thread socket head cap screw features precise Class 3A thread fit per UNRC standards with partial threading extending to minimum 1.16" on the 2" length. Manufacturing complies with ASME B18.3, NAS1352N08-32, and SAE AMS5731/5737 specifications, ensuring dimensional accuracy and performance consistency. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting the latest international standards for hazardous substance restrictions.
