S-92765A214 10-32 x 5/16" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide coating that protects against rust in demanding industrial environments
• Precise thread engagement with Class 3A fit ensuring tighter tolerances and more reliable fastening than standard Class 2A
• Enhanced installation control through hex drive design that prevents cam-out and allows higher torque application
• Optimal surface contact with oval tip design that minimizes component damage while maintaining secure positioning
• Exceptional durability from Rockwell C45 hardened alloy steel that resists wear and maintains clamping force
• Industry-standard compliance meeting ASME B18.3 specifications for consistent performance and interchangeability
• Environmental responsibility with RoHS 3 and REACH compliance for sustainable manufacturing practices

Professional Applications & Engineering Value

This 10-32 UNF Class 3A set screw delivers critical performance in precision assemblies where vibration resistance and positional accuracy are paramount. The black-oxide alloy steel construction provides essential corrosion protection while maintaining the Rockwell C45 hardness needed to withstand repetitive stress cycles. The fine thread spacing of the UNF thread form enables finer adjustment capabilities compared to coarse threads, while the oval tip design distributes clamping force evenly to prevent marring of shaft surfaces. These hex headless set screws are engineered for applications requiring flush mounting in pulleys, gears, and collars where protruding fastener heads would interfere with operation. The right-hand thread direction ensures compatibility with standard installation tools and procedures across industrial maintenance and OEM assembly lines.

Specification Summary & Compliance

This precision fastener features Class 3A thread fit with tighter tolerances than standard Class 2A for superior engagement in critical applications. Manufactured to ASME B18.3 specifications where applicable, the set screw maintains dimensional consistency and interchangeability. The product meets RoHS 3 (2015/863/EU) compliance for restricted substance management and REACH (EC 1907/2006) compliance for chemical safety, supporting responsible manufacturing practices while delivering reliable performance in industrial fastening systems.
