Professional Applications & Engineering Value

This 316 stainless steel socket head cap screw is engineered to address critical challenges in demanding industrial environments where corrosion resistance and mechanical strength are paramount. The combination of passivated finish and UNC coarse thread with Class 3A fit provides exceptional protection against chemical degradation while maintaining precise tolerances for vibration-resistant assemblies. Ideal for machinery, marine equipment, and chemical processing applications, the fully threaded design ensures maximum thread engagement and uniform stress distribution. The hex drive socket head enables high-torque installation in confined spaces, making it particularly valuable for maintenance and assembly operations where accessibility is limited. These features collectively deliver long-term reliability in corrosive or high-stress conditions while reducing maintenance frequency and replacement costs.

Specification Summary & Compliance

This socket head cap screw features precise Class 3A thread fit with UNC coarse thread (5/16"-18) in right-hand direction, manufactured to inch system specifications. The fastener maintains dimensional accuracy with 0.3125" thread diameter and 1" length fully threaded. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance adherence for industrial applications.
