Professional Applications & Engineering Value
This black-oxide alloy steel socket head cap screw is engineered to address common industrial challenges such as vibration-induced loosening and corrosion in demanding settings. The 10-32 UNF fine thread with Class 3A fit delivers precise engagement in tapped holes, ideal for applications in automotive assemblies, precision machinery, and electronic enclosures where reliable fastening is critical. Combined with the split lock washer, it effectively counters rotational forces, reducing the risk of assembly failure. The Rockwell C39 hardness and high tensile strength ensure durability under cyclic loads, making it a trusted choice for OEMs and maintenance teams seeking long-term performance without frequent replacements.
Specification Summary & Compliance
This screw features a 10-32 UNF thread with Class 3A tolerance for accurate fit, fully threaded design, and right-hand direction. Dimensions include a 3/8" length, 5/16" head diameter, and hex drive size of 5/32". The assembly includes a split lock washer with 19/64" OD and 3/64" thickness, all constructed from black-oxide steel. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring adherence to environmental and safety regulations for industrial use.
