Professional Applications & Engineering Value

This 5/8"-11 UNC set screw delivers critical holding power for industrial machinery, automotive components, and precision equipment where vibration resistance is paramount. The Black-Oxide 12L14 steel construction provides durable protection against rust and wear, while the removable swivel tip prevents marring of sensitive surfaces and maintains consistent pressure distribution at up to 10° angles. Engineered with coarse UNC threads and Class 2A fit, it ensures rapid installation and reliable performance in high-stress applications, making it ideal for permanent positioning of gears, pulleys, and collars on rotating shafts.

Specification Summary & Compliance

Manufactured to precise UNC coarse thread standards with Class 2A thread fit for consistent dimensional accuracy. Complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are met for industrial and export applications. The right-hand thread direction and 5/16" hex drive conform to common assembly practices, providing reliable interoperability with standard tools and components.
