Professional Applications & Engineering Value
This black-oxide steel coupling nut solves critical challenges in industrial assembly where corrosion resistance and thread reliability are paramount. The fully threaded UNF fine thread design maintains consistent load distribution across the entire coupling length, preventing stress concentration points that cause failure in high-vibration environments. Engineers specify this ASTM A108 certified component for extending threaded rods in construction frameworks, hydraulic systems, and heavy machinery where Class 2B thread fit ensures precise alignment without galling. The black-oxide surface treatment provides essential protection against oxidation in humid or outdoor applications, while the standardized 3/4"-16 UNF threading guarantees interchangeability across industrial equipment platforms.
Specification Summary & Compliance
Manufactured to ASTM A108 specifications with Class 2B thread fit tolerance for unified fine threads. Threading conforms to UNF 3/4"-16 standards with right-hand direction and full-length coverage. Dimensions include 63/64" OD and 1 1/4" length. Compliant with RoHS 3 (2015/863/EU) under exemption 6(a) for lead in steel alloys and REACH (EC 1907/2006) regulations regarding SVHC substances.
