S-92695A835 5/8"-18 x 3/4" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with Black-Oxide coating, extending service life in demanding industrial environments
• Exceptional holding power achieved through Class 3A thread fit precision, minimizing loosening under vibration
• Maximum grip penetration with 90° cone point design that bites deeply into mating surfaces
• High-strength performance backed by Rockwell C45 hardness rating for heavy-duty applications
• Secure installation enabled by headless hex drive design that prevents protrusion in confined spaces
• Reliable fine threading with 5/8"-18 UNF configuration for precise adjustment and superior clamping force
• Industry-standard compatibility meeting ASME B18.3 specifications for consistent performance across applications

Professional Applications & Engineering Value

This Black-Oxide alloy steel set screw delivers critical engineering solutions for industrial applications requiring permanent, vibration-resistant fastening. The headless design with 5/16" hex drive provides flush mounting in pulleys, gears, and collars where protruding fastener heads are problematic. The 90° cone point creates concentrated pressure that digs into shaft materials, preventing rotational slippage in high-torque environments. With 5/8"-18 UNF fine threads and Class 3A thread fit, this set screw maintains precise positioning in machinery, automotive, and manufacturing equipment where minute adjustments and reliable clamping are essential. The combination of Rockwell C45 hardness and corrosion-resistant coating ensures long-term performance in challenging operating conditions.

Specification Summary & Compliance

Manufactured to exacting Class 3A thread fit tolerances with 5/8"-18 UNF fine threads and right-hand thread direction. This set screw complies with ASME B18.3 dimensional standards and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The product features a 3/4" length, 0.625" thread diameter, and cone point with 90° angle, manufactured from high-strength alloy steel with Black-Oxide surface treatment for enhanced durability and corrosion protection.
