Key Features & Benefits at a Glance
- Exceptional holding power with Class 3A thread fit for secure, vibration-resistant fastening in demanding applications.
- Superior corrosion resistance and wear durability thanks to the Black Oxide finish on high-strength alloy steel.
- Optimized for high-torque installation using the 1/16" hex drive, preventing tool slippage and head stripping.
- Enhanced grip and component alignment from the extended tip design, ensuring precise positioning and reduced loosening.
- Reliable performance under stress with Rockwell C45 hardness, maintaining structural integrity in heavy-duty use.
- Broad industrial compatibility with coarse UNC threads and right-hand direction for quick assembly and disassembly.
- Safe for regulated environments as it complies with RoHS 3 and REACH, meeting global environmental and safety standards.
Professional Applications & Engineering Value
This 5-40 UNC set screw is engineered to address common industrial challenges like component slippage and vibration-induced loosening. The Black Oxide Alloy Steel construction provides excellent resistance to rust and wear, extending service life in harsh conditions. Its extended tip design increases surface contact, improving grip on shafts, collars, and pulleys in machinery, automotive, and aerospace assemblies. The coarse thread and Class 3A fit ensure tight tolerances, reducing the risk of thread damage during repeated adjustments. Ideal for precision equipment, this headless set screw offers a flush finish, preventing interference in compact spaces while delivering consistent, high-strength performance.
Specification Summary & Compliance
This set screw adheres to ASME B18.3 specifications, with precise Class 3A thread fit for accurate engagement and minimal backlash. Dimensions include a 1/8" length, 5-40 UNC coarse thread, and extended tip diameter of 0.083" with tight tolerances. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring it meets stringent environmental and health regulations for industrial use.
