Key Features & Benefits at a Glance
- Enhanced corrosion resistance with black-oxide steel coating, extending service life in harsh industrial environments.
- Superior load distribution due to fully threaded UNC coarse design, ensuring stable connections under heavy loads.
- Reliable thread engagement with Class 2B thread fit, minimizing cross-threading and installation errors.
- Broad compatibility with standard 3/4"-10 UNC components, simplifying sourcing and assembly processes.
- Compliance with ASTM A108 standards, guaranteeing material consistency and mechanical performance.
- Environmental regulation adherence including RoHS 3 and REACH, supporting sustainable procurement policies.
- Optimized dimensions (63/64" OD, 1 1/4" length) for balanced strength and space efficiency in coupling applications.
Professional Applications & Engineering Value
This black-oxide steel coupling nut addresses critical challenges in industrial assembly, where vibration resistance and long-term durability are paramount. The fully threaded right-hand UNC coarse threading ensures maximum thread contact, distributing stress evenly to prevent joint failure in high-torque scenarios like machinery frames, structural supports, and conveyor systems. The black-oxide surface treatment provides a protective layer against rust and wear, reducing maintenance costs in humid or abrasive settings. By meeting ASTM A108 specifications, it delivers consistent tensile strength and dimensional accuracy, making it ideal for heavy-duty coupling applications in construction, automotive, and manufacturing sectors where reliability cannot be compromised.
Specification Summary & Compliance
This coupling nut features precision Class 2B thread fit with UNC coarse threading (3/4"-10) and standard profile, manufactured in accordance with ASTM A108 for material integrity. It complies with RoHS 3 (2015/863/EU) under exemption 6(a) for lead in steel alloys and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are met for industrial use.
