S-92765A562 3/8"-24 x 1 1/2" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide coating, extending service life in harsh industrial environments
• Precise thread engagement with Class 3A UNF fine threads ensuring vibration-resistant, secure fastening
• Exceptional mechanical strength from Rockwell C45 hardened alloy steel, preventing deformation under heavy loads
• Streamlined installation with headless design and 3/16" hex drive, ideal for confined spaces
• Reduced component damage thanks to oval tip design that minimizes surface marring during clamping
• Regulatory compliance assurance meeting ASME B18.3, ASTM F912, RoHS 3, and REACH standards
• Reliable performance in right-hand thread applications requiring fine adjustment and positioning

Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers critical engineering solutions for industrial applications where vibration resistance and positioning accuracy are paramount. The Class 3A UNF fine threads maintain tight tolerances in precision assemblies, while the Rockwell C45 hardness ensures the fastener withstands repetitive stress in machinery, automotive components, and power transmission systems. The headless design with hex drive provides flush mounting in space-constrained applications, and the oval tip distributes clamping force evenly to prevent damage to shafts and collars. These set screws are engineered to solve common industrial challenges of component slippage, thread stripping, and environmental degradation.
