S-92695A768 5/16"-24 x 7/8" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with 90° cone point design that bites deeply into mating surfaces for permanent, vibration-resistant fastening
• Exceptional thread precision with Class 3A fit ensures tighter tolerances and more reliable performance than standard commercial grades
• Enhanced corrosion resistance through black-oxide surface treatment that protects against rust in demanding industrial environments
• Maximum torque transmission via 5/32" hex drive that prevents tool slippage and ensures secure installation even in high-torque applications
• Long-term durability from Rockwell C45 hardened alloy steel construction that maintains structural integrity under heavy loads
• Space-saving design as a headless set screw that fits flush in applications where clearance is limited
• Reliable fine threading with 5/16"-24 UNF configuration providing more threads per inch for improved adjustment precision

Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers exceptional engineering value in precision assembly applications where vibration resistance and permanent positioning are critical. The Class 3A thread fit provides superior dimensional accuracy for high-stakes mechanical systems, while the 90° cone point creates permanent seating in shafts, collars, and pulleys without damaging components. The headless hex drive design solves space constraints in compact assemblies while maintaining full torque capability. Ideal for precision machinery, automotive components, and industrial equipment, this UNF fine thread set screw ensures reliable performance in applications requiring exact positioning and resistance to loosening under dynamic loads. The combination of Rockwell C45 hardness and corrosion-resistant surface treatment makes it suitable for both indoor and moderate outdoor environments.
