Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical engineering solutions for demanding industrial applications where vibration resistance and corrosion protection are paramount. The Class 3A thread fit ensures precise engagement with mating components, eliminating play in machinery assemblies subject to constant stress. The cup tip design concentrates clamping force while minimizing surface marring, making it ideal for precision positioning of gears, pulleys, and collars on shafts. With Rockwell C45 hardness and coarse UNC threads, this fastener maintains its integrity in high-torque applications across manufacturing, automotive, and heavy equipment sectors where reliability cannot be compromised.
Specification Summary & Compliance
Manufactured to exacting ASME B18.3 and ASTM F912 specifications, this set screw maintains Class 3A thread tolerances for superior fit and function. The 1 1/4"-7 UNC coarse thread configuration provides optimal engagement in various materials. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards ensures environmental responsibility while meeting global regulatory requirements for industrial components.
