S-92695A658 5/16"-18 x 7/16" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide coating, extending service life in harsh industrial environments
• Exceptional holding power from 90° cone point design that bites deeply into mating surfaces
• Precise Class 3A thread fit ensures tight tolerances and reliable fastening in critical applications
• High-strength performance with Rockwell C45 hardness for maximum durability under heavy loads
• Easy installation and removal using standard 5/32" hex drive tools
• Space-saving headless design allows for flush mounting in confined spaces
• Coarse UNC threading provides quick assembly and reduced cross-threading risks

Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers exceptional engineering value in demanding industrial applications where vibration resistance and permanent positioning are critical. The 5/16"-18 UNC coarse threads with Class 3A fit maintain precise alignment in pulleys, gears, and collars, while the 90° cone point creates permanent seating that withstands rotational forces. The headless design with hex drive enables installation in space-constrained assemblies common in machinery, automotive, and manufacturing equipment. The combination of Rockwell C45 hardness and corrosion-resistant black-oxide coating ensures reliable performance in environments exposed to moisture, chemicals, and temperature variations, making it ideal for permanent fastening solutions that cannot compromise on security or longevity.
