- Reliable, secure fastening ensured by the Class 2B thread fit, providing consistent engagement and reducing the risk of loosening.
- Quick and easy installation with coarse (UNC) thread spacing and standard external hex drive, saving valuable assembly time.
- High-strength performance for heavy-duty applications, with a substantial 2 1/4" width providing a large bearing surface.
- Guaranteed material integrity and compliance with strict industrial regulations, being fully RoHS 3 and REACH compliant.
- Broad compatibility with standard 1 1/2"-6 UNC male threads, making it a versatile component for various inch-system assemblies.
Professional Applications & Engineering Value
This heavy-duty hex nut is engineered to solve critical challenges in demanding sectors like marine, chemical processing, and outdoor infrastructure. The core of its value lies in the Black-Oxide 316 Stainless Steel material, which provides an exceptional barrier against pitting and corrosion from chlorides and harsh chemicals, significantly reducing maintenance costs and failure rates. The coarse UNC thread and Class 2B thread fit are specifically chosen for robust applications where vibration resistance and rapid assembly are paramount. This combination ensures a durable, long-lasting connection that maintains its integrity under stress, making it an indispensable industrial fastener for structural frameworks, heavy machinery, and piping systems where reliability cannot be compromised.
Specification Summary & Compliance
This hex nut conforms to Unified National Coarse (UNC) thread standards with a Class 2B thread fit for consistent dimensional accuracy and interchangeability. The manufacturing and material composition adhere to major compliance directives, including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006). Key dimensional specifications include a 1 1/2"-6 thread size, a 2 1/4" width across flats, and a 1 9/32" height.
