- Exceptional holding power achieved through Rockwell B80 hardness and Class 3A fine thread fit for vibration-resistant fastening
- Easy installation and removal with 3/16" hex drive design providing secure tool engagement without stripping
- Precise component positioning enabled by cup tip design that creates consistent pressure points on shafts and collars
- Space-saving headless configuration allowing flush mounting where protruding fastener heads are not feasible
- Reliable thread engagement with UNF 3/8"-24 fine threads delivering more contact points for stronger connections
- Industry compliance assurance meeting ASME B18.3 specifications for dimensional accuracy and performance standards
Professional Applications & Engineering Value
This 18-8 stainless steel set screw delivers critical engineering solutions for industrial applications requiring vibration resistance and corrosion protection. The Class 3A thread fit with 3/8"-24 UNF fine threads provides superior clamping force in precision assemblies, while the hex drive design ensures reliable installation torque transmission. The headless configuration and cup tip make it ideal for securing collars, gears, and pulleys on rotating shafts in machinery, automotive, and manufacturing equipment. Its Rockwell B80 hardness maintains structural integrity under repeated stress cycles, preventing loosening in high-vibration environments where standard fasteners would fail.
Specification Summary & Compliance
This precision set screw features 3/8"-24 UNF Class 3A fine threads with exacting dimensional tolerances as specified in ASME B18.3 standards. The 1 1/8" length and 0.375" thread diameter ensure consistent performance across industrial applications. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, guaranteeing safe use in regulated industries while maintaining the material integrity of 18-8 stainless steel throughout its service life.
