Professional Applications & Engineering Value

This 5/8"-11 UNC set screw is engineered to address critical challenges in industrial assembly, such as component slippage and fastener failure under dynamic loads. The Black-Oxide Alloy Steel construction provides a robust barrier against rust and chemical exposure, making it ideal for machinery, automotive, and heavy equipment applications. Its Class 3A thread fit and coarse thread spacing deliver precise engagement and high clamping force, preventing loosening in vibrating systems. The headless hex drive and flat tip enable seamless integration into rotating parts like pulleys and gears, ensuring reliable positioning without protrusions. By meeting ASME B18.3 specifications, this screw guarantees consistency and interoperability in set screw installations, reducing downtime and maintenance costs.

Specification Summary & Compliance

This set screw adheres to Class 3A thread fit tolerances for precise, interference-free assembly, with UNC coarse threads (5/8"-11) and a thread diameter of 0.625". It conforms to ASME B18.3 manufacturing standards and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met.
