Professional Applications & Engineering Value

This headless hex set screw delivers exceptional engineering value in applications requiring secure component positioning without protrusion. The 18-8 stainless steel material offers excellent resistance to rust and corrosion, making it suitable for machinery, automotive assemblies, and outdoor equipment. Its fine UNF threads and Class 3A fit provide tight tolerances that prevent loosening under vibration, a common issue in dynamic industrial settings. The cup point design ensures a firm bite into shafts or hubs, distributing pressure evenly to avoid damage. With a 2" length and right-hand thread, it supports precise axial adjustments in pulleys, gears, and couplings, enhancing overall assembly reliability and lifespan.

Specification Summary & Compliance

This set screw adheres to ASME B18.3 specifications, with a Class 3A thread fit for high precision in UNF 3/8"-24 fine threads. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and material integrity. Dimensions include a thread diameter of 0.375", length of 2", and hex drive size of 3/16", all manufactured to consistent quality standards for reliable industrial use.
