- Enhanced load distribution due to the extra wide profile (2 3/8" width), reducing surface pressure and preventing material damage.
- Superior corrosion resistance from the zinc-plated steel construction, ensuring long-term reliability in harsh industrial environments.
- Quick and easy installation with the coarse UNC thread and Class 2B fit, speeding up assembly while maintaining secure fastening.
- High-strength performance meeting ASME B18.2.2 specifications, providing dependable holding power for heavy-duty applications.
- Compliance with global standards including RoHS 3 and REACH, ensuring safe and environmentally responsible use in regulated industries.
- Optimized for high-torque applications with an external hex drive and right-hand thread, allowing for efficient tightening with standard tools.
Professional Applications & Engineering Value
This heavy-duty extra wide hex nut is engineered to address common challenges in structural and machinery assembly, where vibration resistance and uniform clamping force are critical. The zinc-plated steel material offers excellent protection against rust and corrosion, extending service life in outdoor or high-moisture settings like construction, agricultural equipment, and industrial machinery. Its 1 1/2"-6 UNC coarse thread and Class 2B thread fit ensure reliable engagement with mating bolts, reducing the risk of cross-threading and enabling faster installation in time-sensitive projects. The nut's extra wide profile distributes load over a larger area, minimizing stress concentration and preventing joint failure in high-load scenarios, making it a trusted choice for engineers and procurement specialists seeking durable, standards-compliant fasteners.
Specification Summary & Compliance
This hex nut features precise Class 2B thread fit and adheres to ASME B18.2.2 standards for dimensional accuracy and performance. It is manufactured with coarse UNC threads (1 1/2"-6) and a right-hand thread direction, ensuring compatibility with standard inch-system bolts. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety and environmental responsibility for industrial use.
