Professional Applications & Engineering Value
This black-oxide alloy steel socket head cap screw addresses critical engineering challenges in precision machinery, automotive assemblies, and heavy equipment manufacturing. The 3/8"-16 UNC coarse thread configuration provides rapid installation while maintaining Class 3A thread fit for superior vibration resistance in high-stress environments. The ultra-low socket head profile enables flush mounting in confined spaces without compromising the 140,000 psi tensile strength required for structural applications. Engineered with Rockwell C32 hardness, this fastener withstands repeated torque cycles while the black-oxide surface treatment protects against corrosion in industrial atmospheres, making it ideal for production lines, tooling fixtures, and maintenance operations demanding reliability and precision.
Specification Summary & Compliance
Manufactured to precise dimensional standards with length tolerance of -0.005" to 0.005" and Class 3A thread fit per UNC specifications. The 3/8"-16 coarse thread with right-hand direction ensures compatibility with standard industrial components. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting global manufacturing requirements for hazardous substance restrictions.
