Professional Applications & Engineering Value
This 5/8"-11 UNC square head set screw delivers critical holding power in demanding industrial applications where components must remain securely fixed under constant stress. The coarse thread design provides superior resistance to vibrational loosening in machinery, power transmission systems, and heavy equipment. Manufactured from hardened steel with Rockwell B80 hardness, it maintains structural integrity under high torque loads. The external square drive enables maximum torque application without stripping, while the cup tip creates concentrated pressure points for superior grip on shafts, collars, and gears without causing significant surface damage. This combination of durable materials and precision engineering solves common fastening challenges in manufacturing, automotive, and heavy machinery sectors.
Specification Summary & Compliance
This set screw features 5/8"-11 UNC coarse threads with Class 2A thread fit for precise dimensional tolerance and reliable performance. Manufacturing and dimensional specifications comply with ASME B18.6.2 standards, ensuring interchangeability and quality consistency. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for use in regulated industries and international markets.
