S-92695A739 8-36 x 3/16" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with Class 3A thread fit for precise, vibration-resistant fastening in demanding applications
• Enhanced corrosion resistance from black-oxide coating, extending service life in industrial environments
• Maximum torque transmission through 5/64" hex drive design, preventing tool slippage during installation
• Deep penetration and secure positioning with 90° cone point tip for permanent component alignment
• Exceptional mechanical strength from Rockwell C45 hardened alloy steel, resisting deformation under heavy loads
• Reliable fine thread engagement with 8-36 UNF specification, maintaining consistent clamping force
• Space-saving headless design allowing flush mounting where clearance is limited

Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers critical engineering solutions for permanent component fixation in precision assemblies. The 8-36 UNF fine thread configuration with Class 3A tolerance ensures zero backlash in pulleys, gears, and coupling applications, while the 90° cone point creates permanent witness marks for irreversible positioning. Rockwell C45 hardness provides deformation resistance in high-vibration environments like motor shafts and rotating equipment. The headless design with 5/64" hex drive enables installation in confined spaces while maintaining full torque capability. These industrial set screws are engineered to prevent accidental disassembly in automotive, aerospace, and machinery applications where reliability is paramount.
