Professional Applications & Engineering Value
This 5/16"-24 UNF Class 3A set screw is engineered for precision fastening in machinery, automotive, and aerospace assemblies where vibration resistance and positional accuracy are critical. The black-oxide alloy steel construction provides a protective barrier against rust and chemical exposure, extending service life in harsh conditions. Fine UNF threads with Class 3A tolerance ensure minimal backlash and secure retention in tapped holes, preventing loosening under dynamic loads. The headless design with 5/32" hex drive facilitates easy installation in confined spaces, while the flat tip distributes clamping force evenly, protecting shaft surfaces and maintaining alignment in pulleys, gears, and collars.
Specification Summary & Compliance
This set screw adheres to ASME B18.3 specifications with UNF Class 3A thread fit for precise dimensional accuracy. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory acceptance. Manufactured from hardened alloy steel with Rockwell C45 hardness, it guarantees consistent performance in industrial applications requiring reliable, reusable fastening solutions.
