S-92695A685 5/8"-11 x 3/4" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power with a 90° cone point that bites deeply into materials for secure, vibration-resistant fastening in demanding applications.
• Superior corrosion resistance from the black-oxide finish on alloy steel, extending service life in harsh industrial environments.
• High-strength durability with a Rockwell C45 hardness rating, ensuring the screw withstands high torque and repeated use without stripping or deforming.
• Precise thread engagement thanks to the Class 3A thread fit and coarse UNC thread, enabling quick installation and reliable performance under load.
• Easy installation and removal with a 5/16" hex drive and headless design, allowing flush mounting and access in tight spaces.
• Wide compatibility with standard 5/8"-11 UNC components, making it a versatile choice for machinery, automotive, and assembly line setups.
• Regulatory peace of mind by meeting ASME B18.3 specifications and being RoHS 3 and REACH compliant for safe, global use.

Professional Applications & Engineering Value

This 5/8"-11 UNC set screw is engineered to solve critical fastening challenges in industrial settings, where vibration loosening and material fatigue are common issues. The black-oxide alloy steel construction provides enhanced corrosion resistance, reducing maintenance needs in humid or abrasive environments. Its 90° cone point design ensures maximum grip by concentrating pressure on a small contact area, preventing slippage in shafts, collars, and pulleys. With a coarse thread and Class 3A thread fit, it offers rapid assembly and high load-bearing capacity, ideal for heavy-duty machinery, automotive systems, and precision equipment. The headless style and hex drive facilitate seamless integration into compact assemblies, delivering reliable performance where space is limited and security is paramount.

Specification Summary & Compliance

This set screw adheres to ASME B18.3 standards, ensuring dimensional accuracy and performance reliability. It features a Class 3A thread fit for tight tolerances and a coarse UNC thread (5/8"-11) with a thread diameter of 0.625". The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing it is free from hazardous substances and suitable for international industrial applications.
