Professional Applications & Engineering Value
This 3/8"-16 UNC Class 3A set screw is engineered to address common industrial challenges such as component slippage and corrosion-induced failure. Crafted from black-oxide alloy steel, it offers enhanced resistance to rust and oxidation, making it suitable for machinery, automotive assemblies, and outdoor equipment. The coarse thread spacing and right-hand threading ensure rapid, secure fastening, reducing assembly time and improving productivity. Its hex drive and headless design allow for compact installations in confined spaces, providing reliable torque transmission without protruding parts. Ideal for securing pulleys, gears, and collars, this screw delivers consistent performance in high-vibration environments, minimizing maintenance needs and downtime.
Specification Summary & Compliance
This set screw adheres to UNC thread standards with a Class 3A thread fit for precise dimensional accuracy and superior thread engagement. It features a thread size of 3/8"-16, thread diameter of 0.375", coarse thread spacing, and a length of 3/16". Manufactured to high-quality standards, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for industrial use.
