Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical engineering solutions for industrial applications requiring permanent positioning and vibration-resistant fastening. The extended tip design ensures deeper material penetration, preventing component slippage in high-stress assemblies. With UNC coarse threads and Class 2A thread fit, it maintains precise dimensional stability while accommodating minor misalignments during installation. The external square drive provides superior torque transmission compared to standard drives, making it ideal for heavy machinery, automotive components, and manufacturing equipment where reliable set screw performance is non-negotiable. The Rockwell C45 hardness guarantees consistent performance without stripping or deformation under repetitive stress cycles.
Specification Summary & Compliance
Manufactured to ASTM F912 specifications with Class 2A thread fit ensuring dimensional accuracy across all critical parameters. The UNC coarse thread profile (3/8"-16) maintains industry-standard compatibility while the extended tip features precise diameter (0.25") and length (0.094") tolerances. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees safe usage across global industrial markets.
