S-92695A813 1/2"-13 x 5/8" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with a 90° cone point that bites into materials for a secure, non-slip grip in demanding applications.
• Exceptional durability and corrosion resistance thanks to the black-oxide finish on alloy steel, extending service life in harsh industrial environments.
• High-strength performance with Rockwell C45 hardness, ensuring the screw withstands high torque and resists deformation under load.
• Precise and reliable threading with Class 3A thread fit and UNC coarse threads, providing easy assembly and vibration resistance.
• Easy installation and removal using a standard 1/4" hex drive, allowing for quick maintenance and adjustments in tight spaces.
• Headless design for a flush finish, ideal for applications where protruding fastener heads are not feasible.
• Compliance with industry standards including ASME B18.3, ensuring consistent quality and interoperability in engineering projects.

Professional Applications & Engineering Value

This 1/2"-13 UNC set screw is engineered to address common industrial challenges such as component slippage and fastener failure under high stress. The black-oxide alloy steel construction, combined with a Rockwell C45 hardness, provides excellent wear resistance and strength, making it suitable for heavy-duty machinery, automotive assemblies, and precision equipment. The 90° cone point ensures maximum grip by concentrating force on a small area, preventing loosening from vibrations—a critical feature in dynamic environments. With a right-hand coarse thread and Class 3A thread fit, it offers quick installation and reliable performance in applications requiring repeated adjustments. Ideal for securing gears, pulleys, and collars, this headless set screw delivers consistent fastening solutions while meeting rigorous engineering standards.

Specification Summary & Compliance

This set screw features precise Class 3A thread fit with UNC coarse threads (1/2"-13 thread size) and a length of 5/8". It is manufactured in compliance with ASME B18.3 specifications and adheres to environmental regulations including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring safety and sustainability in industrial use.
