Professional Applications & Engineering Value

This Black Oxide Alloy Steel Set Screw with 3/8"-24 UNF Class 3A threading is engineered to solve critical fastening challenges in industrial machinery, automotive components, and precision equipment. The extended tip design (0.25" diameter) creates positive locking action by digging deeper into mating surfaces, preventing component slippage under extreme vibration conditions. The headless configuration with hex drive enables flush mounting in confined spaces while maintaining high torque capability. The fine thread spacing combined with Class 3A precision fit ensures maximum thread engagement and clamping force distribution, making it ideal for permanent positioning applications where reliability is paramount. The black oxide surface treatment provides corrosion protection without significantly increasing dimensional tolerances.

Specification Summary & Compliance

This set screw features 3/8"-24 UNF fine threads with Class 3A thread fit for precision applications, manufactured to ASME B18.3 specifications (ASTM F912).
