S-92695A140 6-32 x 1/2" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide coating on alloy steel, extending service life in demanding industrial environments
• Exceptional holding power from Class 3A thread fit ensuring tight, secure fastening with minimal vibration loosening
• Precise component positioning with 90° cone point design that bites into mating surfaces for reliable alignment
• Enhanced durability from Rockwell C45 hardness, maintaining structural integrity under repeated torque applications
• Space-saving headless design allowing flush mounting where clearance is limited
• Quick installation and removal with standard 1/16" hex drive compatible with common industrial tools
• Reliable coarse threading (UNC) providing faster assembly and reduced cross-threading risk in production environments

Professional Applications & Engineering Value

This 6-32 UNC set screw delivers critical engineering solutions for industrial applications requiring precise component fixation. The black-oxide alloy steel construction provides essential corrosion protection while maintaining the Rockwell C45 hardness needed for high-stress applications. The 90° cone point design creates positive mechanical locking by embedding into shaft surfaces, preventing rotational slippage in power transmission systems, motor assemblies, and precision machinery. The Class 3A thread fit ensures consistent clamping force distribution, while the headless configuration enables use in confined spaces where traditional fasteners cannot operate. These set screws are engineered to maintain positional accuracy in automated equipment, manufacturing jigs, and assembly fixtures where vibration resistance and reliability are paramount.
