Professional Applications & Engineering Value
This 1/2"-13 UNC alloy steel set screw delivers critical engineering solutions for industrial applications where vibration resistance and permanent positioning are paramount. The combination of Rockwell C45 hardness and coarse thread spacing ensures superior holding power in machinery, automotive components, and heavy equipment assemblies. The square head design with external drive provides excellent torque transmission, preventing cam-out during high-tension applications. The cup tip configuration creates concentrated pressure points that bite into shaft materials, effectively resisting rotational forces and maintaining precise component alignment. These features make it ideal for permanent fastening in pulleys, gears, and collars where reliability cannot be compromised.
Specification Summary & Compliance
This set screw maintains Class 2A thread fit tolerances with UNC coarse threads (1/2"-13) and right-hand thread direction. Manufactured to ASME B18.6.2 specifications with dimensional accuracy including 1½" length, 1/2" head width, and 25/64" head height. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial use.
