Professional Applications & Engineering Value

This 1/4"-28 UNF Class 3A set screw is engineered to address common industrial challenges like component slippage and corrosion-induced failure. Made from 18-8 stainless steel, it resists rust and wear in demanding environments such as machinery, automotive, and electronics. The extended tip and fine thread spacing provide superior clamping force, preventing movement in high-vibration settings. Its hex headless design allows for flush mounting in tight spaces, while the right-hand thread ensures easy integration with standard components. Ideal for precision assemblies, this screw enhances reliability and reduces maintenance needs in industrial set screw applications.

Specification Summary & Compliance

This set screw features a Class 3A thread fit for high precision and adheres to ASME B18.3 standards. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety. Dimensions include a 1/4"-28 UNF thread, 3/8" length, and extended tip with specified tolerances for consistent performance in industrial use.
