Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical engineering solutions for precision machinery and industrial equipment. The Class 3A thread fit maintains tight tolerances in high-vibration environments, preventing loosening in rotating assemblies and power transmission systems. The Rockwell C45 hardness ensures dimensional stability under repetitive stress, while the corrosion-resistant coating protects against industrial contaminants and moisture. The headless design with hex drive enables secure installation in confined spaces, making it ideal for shaft collars, gear hubs, and precision alignment applications where reliability and space optimization are paramount.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit precision for superior engagement. Features 5/16"-24 UNF fine threads with right-hand direction and flat tip configuration. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial markets. The black-oxide surface treatment on alloy steel substrate provides enhanced corrosion protection while maintaining dimensional accuracy per industrial standards.
