Professional Applications & Engineering Value
This 3/4"-10 UNC Class 3A set screw delivers exceptional engineering value in demanding industrial applications where vibration resistance and permanent positioning are critical. The Black-Oxide Alloy Steel construction provides superior corrosion protection, extending service life in challenging environments. The cup point design creates deep indentation in mating components, preventing slippage under heavy loads and vibration. With its hex drive configuration and Class 3A thread fit, this fastener ensures precise installation torque and reliable performance in machinery, automotive, and heavy equipment assemblies. The headless design is particularly valuable in applications requiring flush mounting or where rotational clearance is limited, making it ideal for shaft collars, gears, and pulley systems.
Specification Summary & Compliance
This precision set screw features 3/4"-10 UNC coarse threading with Class 3A tolerance for superior fit and performance. Manufactured to ASME B18.3 specifications with Rockwell C45 hardness rating. The 5/8" length and right-hand thread direction provide optimal engagement. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use across global markets.
