Professional Applications & Engineering Value

This 10-32 UNF set screw is engineered to address critical fastening challenges in precision assemblies, such as securing collars, gears, and pulleys on shafts. The 18-8 stainless steel material offers excellent resistance to rust and corrosion, making it suitable for applications in moist or chemical-exposed environments, including machinery, automotive, and electronics. The headless design and hex drive allow for compact installation without protruding parts, while the 90° cone point bites firmly into surfaces to prevent loosening under vibration—common in motors and rotating equipment. By combining fine threads with a Class 3A fit, this screw ensures tight tolerances and reliable performance in high-precision industrial fastening tasks, reducing maintenance needs and improving operational safety.

Specification Summary & Compliance

This set screw adheres to ASME B18.3 specifications, with a Class 3A thread fit for precise dimensional accuracy and UNF fine threads (10-32 size). It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free of hazardous substances. Additional details include a thread diameter of 0.19", length of 1/4", and cone point angle of 90°, all manufactured to consistent quality standards for reliable industrial use.
