Professional Applications & Engineering Value

Engineered for demanding industrial applications, these 316 stainless steel rounded head Phillips screws address critical challenges in corrosive environments where fastener failure is not an option. The UNF fine thread configuration provides superior resistance to vibrational loosening in machinery, automotive, and marine equipment, while the passivated finish creates an additional protective oxide layer that significantly extends service life in saltwater and chemical exposures. The combination of 80,000 psi tensile strength and fully threaded design ensures uniform stress distribution, making these Class 2A thread fit fasteners ideal for precision assemblies requiring repeated disassembly and reassembly without thread degradation.

Specification Summary & Compliance

This 10-32 UNF 7/8" screw maintains Class 2A thread fit tolerances per UNF standards with complete compliance to ASME B18.6.3 manufacturing specifications. The fastener meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) regulations regarding chemical safety. Manufacturing controls ensure dimensional consistency across rounded head profile geometry, Phillips No. 2 drive configuration, and right-hand thread orientation for reliable interoperability in industrial fastening systems.
