S-92695A420 5/16"-24 x 5/16" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with Class 3A thread fit for tight, vibration-resistant connections in demanding applications
• Enhanced corrosion resistance from black-oxide coating, extending service life in harsh industrial environments
• Maximum torque transmission via 5/32" hex drive, preventing tool slippage and ensuring secure installation
• Precision alignment and penetration with 118° cone point design, ideal for seating securely on shafts and components
• Exceptional durability from alloy steel with Rockwell C45 hardness, maintaining integrity under heavy loads
• Reliable fine thread engagement with 5/16"-24 UNF right-hand threads, providing superior clamping force
• Space-saving headless design allowing flush mounting where clearance is limited

Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers critical performance in precision assemblies where vibration resistance and positional accuracy are paramount. The Class 3A UNF fine threads ensure minimal backlash and superior clamp load distribution, effectively preventing loosening in rotating machinery, motor shafts, and gear assemblies. The 118° cone point concentrates force for positive seating on flat or curved surfaces, while the headless hex drive design enables installation in confined spaces without protrusion. Engineered to ASME B18.3 specifications, it provides reliable set screw performance for OEM and MRO applications requiring repeatable, high-strength fastening.

Specification Summary & Compliance

This set screw features 5/16"-24 UNF fine threads with Class 3A fit for precision tolerance, manufactured from alloy steel hardened to Rockwell C45. The 5/32" hex drive and headless cone point (118° angle) design complies with ASME B18.3 standards. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial markets.
