S-92695A766 5/16"-24 x 1/4" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide coating on alloy steel for extended service life in harsh environments
• Precise thread engagement with UNF Class 3A fine threads ensuring vibration-resistant, secure fastening in critical assemblies
• Maximum torque transmission through 5/32" hex drive design, preventing tool slippage and damage during installation
• Enhanced component penetration with 118° cone point angle for deeper bite and superior resistance to loosening under dynamic loads
• Exceptional mechanical strength from Rockwell C45 hardness, maintaining dimensional stability under high stress conditions
• Space-saving headless design allowing flush mounting in confined spaces while maintaining full fastening functionality
• Regulatory compliance assurance meeting ASME B18.3 standards for dimensional accuracy and material quality

Professional Applications & Engineering Value

This 5/16"-24 UNF Class 3A set screw delivers critical engineering solutions for industrial applications requiring precision alignment and permanent component positioning. The black-oxide alloy steel construction provides superior corrosion resistance in manufacturing environments while maintaining the Rockwell C45 hardness necessary for high-stress applications. The fine thread configuration ensures maximum thread engagement in softer materials, preventing stripping and maintaining clamping force in vibrating machinery. The 118° cone point design penetrates deeply into shaft materials, creating permanent seating that resists rotational forces in pulley systems, gear assemblies, and coupling applications. Engineered for hex drive installation, this headless fastener enables precise torque application in confined spaces where traditional fasteners cannot operate effectively.

Specification Summary & Compliance

Manufactured to ASME B18.3 specifications with UNF Class 3A thread fit for precision dimensional accuracy. The 5/16"-24 fine thread configuration ensures optimal performance in demanding applications. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Features right-hand thread direction with 1/4" length and 5/32" hex drive for standardized installation procedures across industrial applications.
