Professional Applications & Engineering Value
This heavy-duty extra wide hex nut is engineered to address critical challenges in demanding industrial settings. Constructed from 316 Stainless Steel, it provides exceptional resistance to pitting and crevice corrosion, making it suitable for marine, chemical processing, and offshore applications where moisture and aggressive chemicals are present. The coarse UNC thread design ensures rapid assembly and disassembly, while the extra wide profile distributes clamping force evenly across surfaces, preventing joint failure in structural connections, heavy machinery, and large-scale fabrication projects. Its ASTM Grade 8M strength rating and Class 2B thread fit deliver reliable performance in high-vibration environments, reducing maintenance needs and downtime.
Specification Summary & Compliance
This nut features a 1 1/4"-7 UNC coarse thread with Class 2B thread fit for precise dimensional accuracy. It meets ASTM A194 manufacturing specifications and is rated ASTM Grade 8M for mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it adheres to environmental and safety standards for industrial components.
