Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical performance in precision machinery, automotive systems, and industrial equipment where vibration resistance and positional security are paramount. The Class 3A thread fit ensures zero backlash in high-speed applications, while the fine UNF threads (5/16"-24) provide superior load distribution compared to coarse threads. The headless design with hex drive allows installation in tight spaces where conventional screws cannot fit, making it ideal for shaft collars, gears, and precision adjustment mechanisms. The corrosion-resistant black-oxide finish protects against industrial atmospheres and lubricants, extending maintenance intervals in demanding applications.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with precise Class 3A thread tolerances for superior fit. 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 markets. The Rockwell C45 hardness rating guarantees consistent performance under mechanical stress.
