Professional Applications & Engineering Value

This 6-32 UNC set screw is engineered for precision fastening in machinery, automotive, and electronics assembly. The black-oxide alloy steel construction offers excellent resistance to rust and wear, extending service life in high-stress conditions. Its coarse thread spacing and Class 3A thread fit provide tight tolerances that prevent backlash, crucial for components subject to vibration. The soft brass tip eliminates surface scoring on shafts or gears, making it ideal for adjustable positioning without compromising integrity. Designed as a headless set screw with a hex drive, it enables flush mounting in space-constrained applications, ensuring reliable performance in industrial settings where durability and precision are paramount.

Specification Summary & Compliance

This set screw features a 6-32 UNC thread with Class 3A thread fit for high precision, 1/4" length, and coarse thread spacing. It meets ASME B18.3 specifications for dimensional accuracy and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industry-standard reliability.
