Professional Applications & Engineering Value

This M12 set screw delivers critical engineering solutions for industrial applications requiring permanent positioning and torque transmission. The alloy steel construction, hardened to Rockwell C39, provides exceptional resistance to shear forces and fatigue in high-vibration environments like motor shafts, gear assemblies, and rotating machinery. The ball tip design concentrates clamping force while minimizing galling on precision surfaces, making it ideal for securing collars, pulleys, and bearings without damaging expensive components. With its coarse thread pitch and Class 6g fit, this hex headless screw maintains reliable grip under dynamic loads, solving common challenges of component slippage and positional drift in mechanical systems.

Specification Summary & Compliance

This metric set screw features M12 x 1.75mm coarse threading with Class 6g tolerance per ISO standards, ensuring precise dimensional accuracy. The 42mm length and 6mm hex drive provide standardized installation compatibility. Manufacturing complies with RoHS 3 (2015/863/EU) regulations with exemption 6(a) for lead as an alloying element in steel, meeting international environmental requirements for industrial components.
