Professional Applications & Engineering Value
Engineered for industrial machinery, heavy equipment assembly, and precision tooling applications, these socket head cap screws deliver critical performance where standard fasteners fail. The zinc-plated alloy steel construction provides essential corrosion protection in manufacturing environments exposed to moisture and chemicals, while the Class 3A thread fit ensures vibration-resistant connections in dynamic systems. The UNC coarse thread design enables rapid installation in production lines, reducing assembly time without compromising the 170,000 psi tensile strength needed for structural applications. The standard socket head profile with 5/16" hex drive accommodates common tooling while maximizing torque capability for high-clamp-force requirements.
Specification Summary & Compliance
Manufactured to exacting Class 3A thread fit tolerances with UNC 3/8"-16 coarse thread specifications. Fully compliant with ASTM A574 manufacturing standards for socket head cap screws. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for restricted substances. Features right-hand thread direction and fully threaded design with 0.375" thread diameter and 3/4" length.
