Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical engineering solutions for industrial applications requiring precision fastening and corrosion protection. The UNF fine thread configuration with Class 3A tolerance ensures zero-backlash mounting in precision machinery, while the headless design with 7/32" hex drive enables flush installation where protruding fasteners are unacceptable. The Rockwell C45 hardness provides exceptional shear strength for permanent positioning applications in automotive, aerospace, and heavy equipment assemblies. The black-oxide surface treatment creates a protective barrier against oxidation and chemical exposure, making these set screws ideal for demanding environments where reliability cannot be compromised.
Specification Summary & Compliance
Manufactured to exacting standards with UNF 7/16"-20 thread featuring Class 3A thread fit for precision applications. The fine thread spacing and 0.437" thread diameter ensure optimal engagement strength. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and global market acceptance. The 7/32" length and right-hand thread direction provide standardized installation across industrial fastener systems.
