Professional Applications & Engineering Value
Engineered for heavy-duty coupling applications, this black-oxide steel nut solves critical challenges in structural assembly and machinery maintenance. The fully threaded UNC coarse profile provides maximum thread engagement depth, eliminating the weak points common in partially threaded connectors. Its Class 2B thread fit maintains precise tolerances while accommodating minor misalignments in field installations. The external hex drive design enables high-torque installation in confined spaces where socket access is limited. Ideal for connecting threaded rods in construction frameworks, extending hydraulic cylinder rods, and assembling industrial machinery where vibration resistance and corrosion protection are paramount. The combination of coarse threading and right-hand direction ensures compatibility with standard industrial components while providing rapid assembly in time-sensitive maintenance operations.
Specification Summary & Compliance
Manufactured to UNC thread standards with Class 2B thread fit for consistent engagement accuracy. Dimensions include 7/16"-14 thread size with coarse thread spacing, 1-3/4" length, and 5/8" width across flats. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. The black-oxide surface treatment provides supplemental corrosion protection while maintaining dimensional stability under mechanical stress.
