S-92695A679 1/2"-13 x 1 1/4" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide coating, extending service life in harsh industrial environments
• Exceptional holding power from 90° cone point tip that bites deeply into mating surfaces for secure component positioning
• Precise Class 3A thread fit ensures tighter tolerances and more reliable assembly than standard Class 2A fasteners
• High-strength performance with Rockwell C45 hardness rating that maintains integrity under heavy mechanical stress
• Easy installation and removal through 1/4" hex drive design, compatible with standard industrial tools
• Reliable coarse threading (UNC 1/2"-13) provides faster assembly and reduced cross-threading risk in production environments
• Space-saving headless design allows flush mounting where clearance is limited without compromising strength

Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers critical engineering solutions for industrial applications requiring permanent component positioning. The 90° cone point creates concentrated pressure that prevents slippage in pulleys, gears, and collars, while the Class 3A UNC threads maintain precise alignment in high-vibration environments. The Rockwell C45 hardness ensures the fastener withstands repeated adjustments without deformation, making it ideal for machinery maintenance, automotive assemblies, and manufacturing equipment where reliable locking capability is essential. The corrosion-resistant black-oxide finish further enhances durability in challenging operating conditions.
