Professional Applications & Engineering Value

These 0-80 UNF zinc-plated steel rounded head screws deliver critical performance advantages in precision engineering applications where space constraints and corrosion resistance are paramount. The fine thread spacing and Class 2A thread fit ensure vibration-resistant fastening in electronic enclosures, instrumentation, and small mechanical assemblies. The zinc-plated steel construction provides essential protection against environmental degradation while maintaining the 60,000 psi tensile strength required for structural integrity. The combination of Phillips drive and pan head design offers reliable installation in confined spaces common in aerospace components, medical devices, and telecommunications equipment where consistent clamping force and corrosion protection are non-negotiable requirements.

Specification Summary & Compliance

Manufactured to exacting ASME B18.6.3 specifications with Class 2A thread fit tolerances for precision assembly. The UNF 0-80 thread form with fine pitch ensures secure fastening in thin materials. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and global market accessibility. The fully threaded design maintains consistent mechanical properties throughout the 5/32" length, while the Rockwell B70 hardness rating confirms material integrity under operational stresses.
