S-92695A406 5/16"-18 x 3/4" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide coating, extending service life in demanding industrial environments
• Exceptional holding power from the 90° cone point design that bites deeply into mating surfaces for secure, permanent positioning
• High-strength performance backed by Rockwell C45 hardness and alloy steel construction, resisting deformation under heavy loads
• Precise thread engagement with Class 3A fit and UNC coarse threads, ensuring reliable installation and vibration resistance
• Streamlined installation using the hex drive design, allowing high torque application in confined spaces without protruding heads
• Regulatory compliance assurance meeting ASME B18.3, RoHS 3, and REACH standards for quality and environmental safety
• Optimized for right-hand applications with coarse thread spacing that enables quick assembly in standard industrial equipment

Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers critical engineering solutions where permanent component positioning is essential. The headless design with hex drive enables flush mounting in pulleys, gears, and collars while the 90° cone point creates concentrated pressure to prevent shaft slippage in high-torque applications. Manufactured to Class 3A thread fit with UNC coarse threads, it maintains precise tolerances for vibration-resistant fastening in industrial machinery, automotive systems, and power transmission equipment. The combination of Rockwell C45 hardness and protective black-oxide finish ensures durability against wear and environmental exposure, making it ideal for demanding applications requiring reliable, long-term fastening performance.

Specification Summary & Compliance

This set screw features 5/16"-18 UNC coarse threads with Class 3A thread fit for precision engagement, measuring 3/4" in length with a 90° cone point. Manufactured according to ASME B18.3 specifications using black-oxide treated alloy steel with Rockwell C45 hardness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors.
