Professional Applications & Engineering Value
This 3/4"-16 UNF Class 3A set screw delivers critical engineering solutions for high-stakes industrial applications where alignment precision and vibration resistance are paramount. The 18-8 stainless steel material provides inherent corrosion resistance, eliminating failure risks in humid or chemical-exposed environments like marine equipment and food processing machinery. Its fine thread spacing and Class 3A thread fit create superior clamping force distribution, preventing loosening in dynamic systems such as motor shafts, gear assemblies, and precision tooling. The hex headless design with cup tip ensures secure, mar-free fastening in rotating components, making it indispensable for OEMs and maintenance teams requiring reliable, long-term set screw performance without frequent re-tightening.
Specification Summary & Compliance
Manufactured to exact ASME B18.3 specifications with Class 3A thread fit for precision tolerance. Features 3/4"-16 UNF fine threads with right-hand direction and 1-1/2" length. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in regulated industries.
