S-92695A683 5/8"-11 x 1/2" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with a 90° cone point that bites deeply into materials for secure, vibration-resistant fastening.
• Exceptional durability and wear resistance thanks to the Rockwell C45 hardened black-oxide alloy steel construction.
• Precise and reliable thread engagement ensured by the Class 3A thread fit for high-strength applications.
• Easy installation and high torque capability with a 5/16" hex drive in a headless design for flush mounting.
• Optimized for quick assembly with coarse 5/8"-11 UNC threads that are less prone to cross-threading.
• Corrosion-resistant black-oxide finish provides a protective layer, extending the screw's service life in various environments.
• Guaranteed quality and safety through compliance with ASME B18.3, ASTM F912, RoHS 3, and REACH standards.

Professional Applications & Engineering Value

This black-oxide alloy steel set screw is engineered to solve critical fastening challenges in demanding industrial settings. Its headless design and hex drive allow for a flush, tamper-resistant installation, ideal for machinery where protruding components are not feasible. The 90° cone point and Class 3A thread fit work in tandem to provide exceptional grip and resistance to loosening under vibration, making it perfect for securing collars, gears, and pulleys on shafts. Manufactured from Rockwell C45 hardened material, it withstands high stress and repetitive loads, ensuring long-term reliability in automotive, aerospace, and heavy equipment applications. The coarse UNC threads facilitate faster assembly, reducing labor time while maintaining a robust connection.

Specification Summary & Compliance

This set screw features a 5/8"-11 UNC coarse thread with a Class 3A precision thread fit, ensuring tight tolerances for high-strength assemblies. It has a length of 1/2", a thread diameter of 0.625", and a 5/16" hex drive. The product conforms to ASME B18.3 and ASTM F912 manufacturing specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, guaranteeing safety and sustainability in industrial use.
