S-92695A822 1/2"-20 x 3/4" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with a 90° cone point that bites into surfaces for maximum resistance against loosening under vibration and torque.
• Exceptional thread precision with a Class 3A fit ensures tight, secure fastening with minimal play, ideal for high-precision assemblies.
• Enhanced durability and corrosion resistance from the Black-Oxide Alloy Steel material, extending service life in demanding industrial environments.
• High-strength performance backed by Rockwell C45 hardness, providing reliable mechanical strength for heavy-duty applications.
• Easy and secure installation using the 1/4" hex drive, allowing for high-torque application without head protrusion in confined spaces.
• Reliable fine thread spacing (UNF) offers improved adjustment precision and greater tensile strength compared to coarse threads.
• Broad compliance with ASME B18.3, RoHS 3, and REACH standards ensures quality, safety, and environmental responsibility.

Professional Applications & Engineering Value

This Black-Oxide Alloy Steel set screw is engineered to address critical challenges in industrial machinery, automotive, and precision equipment assembly. The headless design with a 1/4" hex drive allows for flush mounting in tight spaces, eliminating interference while enabling high torque application. Its 90° cone point concentrates force for superior grip on shafts, gears, and collars, preventing slippage and maintaining alignment under dynamic loads. The Class 3A UNF fine thread ensures precise engagement and vibration resistance, reducing maintenance needs. Combined with Rockwell C45 hardness, it delivers consistent performance in high-stress environments, making it a reliable choice for engineers seeking durability and precision in set screw applications.
