Professional Applications & Engineering Value
This 10-32 UNF Class 3A set screw is engineered to address critical challenges in industrial assemblies, such as component slippage and vibration-induced loosening. The Black-Oxide alloy steel construction offers enhanced corrosion resistance, making it ideal for machinery exposed to moisture or chemicals. With a fine thread spacing and headless design, it provides a low-profile, secure fastening solution for precision equipment, automotive components, and rotating shafts. The serrations locking mechanism ensures lasting grip without the need for adhesives, reducing maintenance downtime. Its cup point concentrates pressure for superior holding in high-torque applications, delivering reliable performance in demanding environments like manufacturing automation and aerospace systems.
Specification Summary & Compliance
This set screw features a 10-32 UNF thread with Class 3A fit for precise dimensional accuracy, ensuring minimal backlash and secure fastening. It adheres to ASME B18.3 manufacturing specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material integrity in industrial use.
