- Reliable and quick assembly with the coarse UNC thread and right-hand direction, ideal for high-volume applications
- Guaranteed interchangeability and fit ensured by compliance with the rigorous ASME B18.2.2 standard
- Secure and consistent thread engagement with the Class 2B thread fit, minimizing the risk of cross-threading
- Confident global sourcing with full compliance to RoHS 3 and REACH environmental regulations
- Optimized for heavy-duty use with a substantial 1 5/8" width and 63/64" height for demanding mechanical fastening
Professional Applications & Engineering Value
This heavy-duty hex nut is engineered to solve critical challenges in industrial assembly and maintenance. The zinc-plated steel material provides a robust barrier against rust and corrosion, significantly increasing the lifespan of connections in outdoor equipment, structural frameworks, and machinery exposed to moisture. The 1"-8 UNC coarse thread design allows for faster installation and is less prone to clogging with debris compared to fine threads, making it highly efficient for construction, agricultural machinery, and transportation applications. The extra wide profile offers a larger contact surface for wrenches, distributing force more evenly and reducing the risk of tool slippage and damage to the fastener, which is crucial for achieving the high clamping forces required in heavy-duty and industrial fastening scenarios. This combination of features ensures a reliable, long-lasting, and safe fastening solution.
Specification Summary & Compliance
This nut features a 1"-8 UNC coarse thread with a Class 2B thread fit and right-hand direction. Manufacturing and dimensional specifications conform to ASME B18.2.2. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
