Professional Applications & Engineering Value

Engineered for demanding industrial applications, this socket head cap screw combines chrome-plated 18-8 stainless steel construction with Class 3A UNC coarse threads to solve critical fastening challenges. The material's inherent corrosion resistance prevents degradation in moisture-prone environments, while the 70,000 psi tensile strength maintains joint integrity under dynamic loads. The 3/16" hex drive interface allows high-torque installation in confined spaces common in machinery, automotive, and equipment manufacturing. The fully threaded design ensures maximum thread engagement throughout the fastener length, providing superior vibration resistance compared to partial-thread alternatives. This combination of precision engineering and durable materials delivers reliable performance in applications requiring repeated disassembly and reassembly cycles.

Specification Summary & Compliance

This socket head cap screw features precision 1/4"-20 UNC Class 3A threads with coarse spacing for optimal engagement. Manufacturing complies with ASTM B456 specifications for plating quality and material properties. The fastener demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance adherence. Dimensional accuracy meets inch system requirements with 1" length, 3/8" head diameter, and 1/4" head height for consistent interchangeability in industrial applications.
