S-92695A672 3/8"-24 x 5/8" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with Class 3A thread fit for precise, vibration-resistant assemblies
• Exceptional durability from Rockwell C45 hardness, resisting wear in demanding applications
• Enhanced corrosion resistance due to the black-oxide finish on alloy steel
• Secure, flush mounting enabled by the headless design with hex drive for tight spaces
• Reliable component positioning via the 90° cone point that bites into surfaces
• Optimized for fine adjustments with UNF fine threads providing greater clamping force
• Broad industry compliance meeting ASME B18.3, RoHS 3, and REACH standards

Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers critical performance in machinery, automotive, and precision equipment where vibration resistance and positional accuracy are paramount. The headless hex drive design allows for flush installation in confined areas, while the 90° cone point ensures positive seating on shafts and collars to prevent slippage. Manufactured to ASME B18.3 specifications with Class 3A UNF fine threads, it maintains tight tolerances for high-stress applications. The Rockwell C45 hardness and protective finish provide long-term reliability in harsh environments, making it an ideal high-strength fastener for permanent assemblies.

Specification Summary & Compliance

This set screw features 3/8"-24 UNF fine threads with Class 3A fit for precision assembly. It complies with ASME B18.3 manufacturing standards and demonstrates conformity with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The right-hand thread direction and 5/8" length provide consistent performance in industrial fastening systems.
