S-92505A585 5/16"-18 x 1 1/2" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Maximum holding power through extended tip design that creates superior grip in demanding applications
• Exceptional thread precision with Class 3A fit ensuring reliable, vibration-resistant fastening in critical assemblies
• Enhanced corrosion resistance provided by black oxide coating, extending service life in industrial environments
• Superior mechanical strength from Rockwell C45 hardened alloy steel, preventing deformation under heavy loads
• Optimized installation efficiency with 5/32" hex drive allowing secure tool engagement and precise torque application
• Reliable coarse thread performance with UNC 5/16"-18 configuration for quick assembly and disassembly
• Industry compliance assurance meeting ASME B18.3 standards for consistent quality and dimensional accuracy

Professional Applications & Engineering Value

This black oxide alloy steel set screw delivers exceptional engineering value in industrial applications where vibration resistance and permanent positioning are critical. The extended tip design with precise 0.082" length creates concentrated point pressure, preventing component slippage in shafts, collars, and pulleys. The Class 3A thread fit ensures minimal clearance between mating parts, eliminating play in precision machinery and automation equipment. The Rockwell C45 hardness provides the necessary toughness to withstand repeated stress cycles without thread deformation. As a headless set screw with right-hand UNC coarse threads, it offers streamlined installation in confined spaces while maintaining the structural integrity of assembled components across manufacturing, automotive, and heavy equipment applications.
