Professional Applications & Engineering Value
This 3/8"-16 UNC Class 3A stainless steel set screw is engineered to address critical challenges in industrial settings, such as vibration-induced loosening and misalignment. The 18-8 stainless steel material offers excellent resistance to rust and corrosion, making it suitable for outdoor, marine, or chemical-exposed environments. With a coarse thread and Class 3A fit, it ensures a precise, tight hold that minimizes backlash in assemblies like shafts, pulleys, and gears. The hex drive allows for easy installation with standard tools, reducing assembly time while the cup point provides a biting action that prevents rotational slippage under high stress. Ideal for machinery, automotive, and aerospace applications, this set screw delivers reliable performance where durability and secure fastening are paramount.
Specification Summary & Compliance
This set screw adheres to ASME B18.3 standards, ensuring dimensional accuracy and interchangeability. It features a UNC coarse thread with Class 3A fit for precise tolerances, a length of 1 1/4", and a thread size of 3/8"-16. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) confirms it is free from hazardous substances, supporting safe and sustainable industrial use.
