Professional Applications & Engineering Value
These 8-32 UNC set screws deliver exceptional engineering value in precision assembly applications where reliable shaft positioning is critical. The 18-8 stainless steel composition provides excellent corrosion resistance for demanding environments including marine, food processing, and outdoor equipment. The cup point design creates deep indentation in mating surfaces, preventing rotational slip and maintaining permanent alignment in pulleys, gears, and collars. With Class 3A thread fit precision and right-hand UNC coarse threads, these hex headless set screws ensure consistent clamping force while the 5/64" hex drive facilitates installation in confined spaces. The combination of Rockwell B80 hardness and 1 1/8" length makes these industrial fasteners ideal for high-vibration applications requiring sustained holding power.
Specification Summary & Compliance
This set screw features precision 8-32 UNC coarse threads with Class 3A fit for tight tolerance applications. Manufacturing complies with ASME B18.3 specifications ensuring dimensional accuracy and performance reliability. The product meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) regulations for environmental safety. Thread direction is right-hand with standard 0.164" thread diameter and 1 1/8" length for consistent industrial application requirements.
