- Enhanced corrosion protection from the black-oxide surface finish, increasing service life in various industrial environments.
- Secure, flush installation with a headless design and cup tip, providing a firm grip without protruding components.
- Easy installation and removal using the 1/16" hex drive, allowing for efficient assembly with standard tools.
- Broad compatibility with UNC coarse 6-32 threads, making it suitable for a wide range of right-hand applications.
Professional Applications & Engineering Value
This 6-32 UNC Class 3A set screw is engineered to address common industrial challenges like component slippage and fastener failure in high-stress environments. Crafted from black-oxide alloy steel, it offers robust resistance to corrosion and mechanical stress, ideal for machinery, automotive, and electronics assemblies. The serrations locking feature ensures a permanent hold by embedding into the shaft, eliminating the need for additional locking devices and reducing maintenance. With a cup tip design, it provides concentrated clamping force, while the coarse thread facilitates quick installation. Complying with ASME B18.3 standards, this screw delivers precision and reliability, enhancing the longevity and safety of your equipment in heavy-duty applications.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including UNC thread with Class 3A fit for superior accuracy and a 6-32 thread size. It meets ASME B18.3 specifications for manufacturing consistency and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity. The Rockwell C45 hardness and black-oxide finish further validate its durability and performance in industrial settings.
