S-92695A804 7/16"-20 x 5/8" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide coating protecting against rust and extending service life in harsh industrial environments
• Precise thread engagement with Class 3A UNF fine threads ensuring tighter tolerances and more reliable fastening than standard threads
• Exceptional hardness and strength at Rockwell C45 for high clamp load retention and resistance to wear under vibration
• Secure installation and removal with 7/32" hex drive providing positive torque transmission without cam-out
• Effective positioning and alignment with 90° cone point tip that bites into shafts for permanent component location
• Space-saving headless design allowing flush mounting where protruding fasteners aren't feasible
• Regulatory compliance assurance meeting major industrial and environmental standards for global supply chain integration

Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers critical performance in demanding applications where vibration resistance and permanent positioning are paramount. The UNF Class 3A fine threads provide superior holding power in precision assemblies, while the 90° cone point creates positive engagement with shaft materials without causing excessive damage. The Rockwell C45 hardness ensures the screw maintains its clamping force in high-stress environments, making it ideal for industrial machinery, power transmission systems, and precision equipment where components must remain securely positioned despite constant operational stresses. The headless hex drive design offers reliable installation in confined spaces where traditional fasteners cannot be accommodated.
