Professional Applications & Engineering Value
Engineered for precision assemblies requiring reliable vibration resistance, these black-oxide alloy steel socket head cap screws with integrated split lock washers solve critical fastening challenges in machinery, automotive, and industrial equipment. The Class 3A UNF fine thread configuration ensures zero-backlash fitment in tapped holes, while the Rockwell C39 hardness rating maintains thread integrity through repeated disassembly cycles. The black-oxide surface treatment provides corrosion protection without dimensional interference, making these fully threaded fasteners ideal for applications where 180,000 psi tensile strength and consistent clamping force are essential for structural integrity and operational safety.
Specification Summary & Compliance
Manufactured to precise inch system dimensions with Class 3A thread fit tolerance per UNF standards. Features right-hand fine threads (10-32) with fully threaded 1" length and standard hex socket drive (5/32"). Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
