Professional Applications & Engineering Value

This 8-32 UNC set screw is engineered to address critical challenges in industrial assembly, such as component slippage and corrosion-induced failure. The 18-8 Stainless Steel material provides excellent resistance to rust and chemical exposure, making it suitable for outdoor equipment, machinery, and automotive systems. Its hex headless design with a 5/64" drive allows for a clean, flush finish while enabling high torque application without protrusion. The Class 3A thread fit and coarse thread spacing ensure a tight, secure fit that minimizes loosening under vibration, enhancing the reliability of shaft collars, gears, and pulleys. This combination of flat tip geometry and robust construction delivers consistent clamping force, solving alignment and retention issues in precision engineering applications.

Specification Summary & Compliance

This set screw adheres to precise dimensional standards, including a Class 3A thread fit for superior accuracy and a 1/4" length. It conforms to the UNC thread type (8-32 size) with coarse spacing and right-hand direction, manufactured per ASME B18.3 specifications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance adherence for global industrial use.
