S-92695A763 5/16"-18 x 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 demanding industrial environments.
• High-strength fastening provided by alloy steel construction and Rockwell C45 hardness, resisting deformation under heavy loads.
• Precise thread engagement with Class 3A UNC coarse threads, ensuring reliable, vibration-resistant connections.
• Secure, flush mounting enabled by the headless design and 90° cone point, ideal for permanent positioning applications.
• Easy installation and removal with the 5/32" hex drive, allowing for high-torque application in confined spaces.
• Broad regulatory compliance including RoHS 3 and REACH, ensuring safety and environmental standards are met for global supply chains.
• Optimized for high-vibration environments due to the coarse thread pitch and cone point design, preventing loosening.

Professional Applications & Engineering Value

This black-oxide alloy steel set screw is engineered to address critical challenges in machinery assembly, automotive components, and heavy equipment. The Class 3A UNC coarse threads provide excellent grip and resistance to vibrational loosening, a common failure point in dynamic systems. The 90° cone point bites securely into shafts or hubs, creating a permanent, semi-permanent alignment without protruding heads. Manufactured to ASME B18.3 and ASTM F912 specifications, it delivers consistent dimensional accuracy and mechanical properties, reducing the risk of assembly errors and component failure. The black-oxide finish adds a layer of corrosion resistance, making it suitable for applications exposed to moisture, oils, and industrial chemicals, thereby extending maintenance intervals and improving overall system reliability.

Specification Summary & Compliance
