S-94495A239 10-32 x 1/2" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Secure, vibration-resistant locking with a Nylon Patch thread locker that maintains integrity from -50° to 250° F, reducing loosening in dynamic applications.
• Exceptional durability and corrosion resistance due to the Black-Oxide finish on Alloy Steel, extending service life in harsh industrial environments.
• Precise, reliable thread engagement with UNF Class 3A fine threads, ensuring tight fits and minimal risk of cross-threading in critical assemblies.
• High-strength performance backed by Rockwell C45 hardness, providing consistent clamping force and resistance to wear under load.
• Easy installation and removal using a 3/32" Hex drive in a headless design, allowing flush mounting and access in confined spaces.
• Flat tip design offers concentrated contact pressure for secure positioning of components on shafts or hubs without marring surfaces excessively.
• Compliance with industry standards including ASME B18.3 and ASTM F912, ensuring interoperability and quality for engineering projects.

Professional Applications & Engineering Value

This 10-32 UNF Class 3A set screw is engineered to address common industrial challenges like vibration-induced loosening and component slippage in machinery. Crafted from Black-Oxide Alloy Steel, it combines high tensile strength with enhanced corrosion resistance, ideal for automotive, aerospace, and manufacturing equipment where reliability is critical. The Nylon Patch thread locker provides a chemical-free, reusable locking mechanism that withstands temperature fluctuations from -50° to 250° F, eliminating the need for additional adhesives. With a fine thread spacing and Class 3A fit, it ensures precise alignment and secure fastening in right-hand thread applications, reducing maintenance downtime and improving overall assembly integrity in headless set screw configurations.
