Professional Applications & Engineering Value
This black-oxide steel flange nut delivers critical engineering solutions where vibration resistance and corrosion protection are paramount. The integrated 45/64" flange diameter distributes clamping force across a wider surface area, preventing surface damage and maintaining joint integrity in heavy-duty industrial applications. The external 12-point drive configuration allows for higher torque application in confined spaces, while the Class 3B UNF fine threads provide superior thread engagement for precision assemblies in automotive, machinery, and structural applications where vibration-induced loosening poses significant operational risks.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 3B thread fit for superior thread engagement and UNF fine thread specifications (7/16"-20). Features standard right-hand thread direction and complies with industrial fastener standards. The black-oxide surface treatment provides corrosion resistance while maintaining dimensional integrity. Engineered for compatibility with standard 12-point external drive tools and manufactured to meet quality specifications for industrial fastener applications.
