S-91375A157 6-32 x 2" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide coating on alloy steel, extending service life in demanding environments.
• Exceptional holding power ensured by the cup tip design, which bites into surfaces for secure, vibration-resistant fastening.
• High-strength performance with Rockwell C45 hardness, providing reliable durability under heavy loads and stress.
• Precise, reliable fit due to UNC coarse threads and Class 3A thread fit, minimizing the risk of cross-threading and ensuring consistent engagement.
• Easy installation in confined spaces with the headless design and 1/16" hex drive, allowing for flush mounting and tool accessibility.
• Broad industrial compliance meeting ASME B18.3 specifications, ensuring interchangeability and reliability in mechanical assemblies.
• Environmentally safe usage with RoHS 3 and REACH compliance, free from hazardous substances for global supply chain integration.

Professional Applications & Engineering Value

This 6-32 x 2" black-oxide alloy steel set screw is engineered to address critical challenges in industrial assembly, such as component slippage and corrosion-induced failure. The UNC coarse threads and Class 3A fit provide tight tolerances that resist loosening under vibration, making it ideal for machinery, automotive, and aerospace applications where precision is paramount. The headless design with hex drive allows for seamless integration into tight spaces, while the cup tip concentrates pressure to prevent shaft damage and enhance grip. Made from hardened alloy steel and treated with a protective black-oxide finish, it withstands harsh conditions without compromising on Rockwell C45 hardness, ensuring long-term reliability and reduced maintenance costs.
