Professional Applications & Engineering Value
This 5/16"-24 coupling nut solves critical alignment and connection challenges in industrial assembly lines and heavy machinery. The black-oxide steel construction provides essential corrosion protection where moisture or chemicals are present, while the UNF fine threading maintains joint integrity under constant vibration. Engineers specify this fully threaded coupling nut for extending threaded rods or joining components where standard nuts can't reach, with the Class 2B fit ensuring consistent torque values and preventing loosening in dynamic applications. The combination of ASTM A276 material standards and precise inch-dimensioning makes it ideal for maintenance, equipment manufacturing, and structural frameworks requiring dependable, long-lasting connections.
Specification Summary & Compliance
Manufactured to Class 2B thread fit tolerances with UNF fine threading (5/16"-24) in right-hand direction. Meets ASTM A276 material specifications with black-oxide surface treatment. Dimensions: 27/64" OD × 3/4" 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.
