Professional Applications & Engineering Value
Engineered for precision and reliability, this 6-32 UNC thread socket head cap screw with black-oxide alloy steel construction addresses critical challenges in machinery, automotive, and heavy equipment assembly. The coarse thread spacing and fully threaded design enable quick engagement and uniform stress distribution, reducing the risk of cross-threading in high-vibration environments. Paired with a split lock washer, it effectively counters rotational loosening, making it ideal for dynamic load applications where fastener integrity is paramount. Its 180,000 psi tensile strength and Rockwell C39 hardness ensure long-term performance, minimizing maintenance downtime and enhancing operational safety in industrial fastening systems.
Specification Summary & Compliance
This screw adheres to UNC thread standards with a precise Class 3A thread fit for consistent engagement. Dimensions include a 3/8" length, 6-32 thread size, and 7/64" hex drive. Manufactured from alloy steel with a black-oxide surface treatment, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory alignment for industrial use.
