S-92695A677 3/8"-24 x 1 1/2" 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
• Precise Class 3A thread fit ensures tighter tolerances and secure fastening in critical applications
• High-strength Rockwell C45 hardness provides excellent wear resistance and prevents deformation under load
• 90° cone point design delivers maximum gripping force and prevents component slippage
• Headless hex drive configuration allows for flush mounting in space-constrained assemblies
• Fine thread spacing (UNF) offers improved vibration resistance and better torque control
• Full regulatory compliance with ASME, ASTM, RoHS 3 and REACH standards for global market acceptance

Professional Applications & Engineering Value

This black-oxide alloy steel set screw with Class 3A UNF fine threads addresses critical engineering challenges in precision assemblies. The 90° cone point creates deep penetration into mating surfaces, effectively preventing rotational slip in pulleys, gears, and collars. The headless hex drive design enables flush installation where protruding fasteners are unacceptable, while the Rockwell C45 hardness maintains dimensional stability under repeated torque applications. Ideal for industrial machinery, automotive components, and precision equipment, this corrosion-resistant set screw delivers reliable performance in demanding environments where vibration resistance and precise positioning are paramount.
