• Wide compatibility with 2" to 4 1/2 UNC coarse threaded bolts, making it a versatile component for various industrial assemblies.
• Secure and efficient installation using standard wrenches on its external hex drive, facilitating quick and easy maintenance.
• Safe for regulated environments as it is fully RoHS 3 and REACH compliant, meeting strict international substance restrictions.

Professional Applications & Engineering Value

This Grade 8 steel hex nut is engineered to solve critical challenges in heavy-duty industrial applications, including construction machinery, structural steelwork, and high-pressure pipeline systems. Its thin profile is a key advantage, enabling use in confined spaces where a standard nut's height is prohibitive, thus expanding design possibilities. The coarse UNC thread and Class 2B fit ensure rapid assembly and a secure, vibration-resistant connection, significantly reducing the risk of loosening under dynamic loads. Manufactured from high-strength steel, this ASME B18.2.2 compliant fastener delivers the reliability needed to maintain structural integrity and safety in critical assemblies, preventing costly downtime and failures.

Specification Summary & Compliance

This hex nut conforms to ASME B18.2.2 specifications, ensuring precise dimensional accuracy. The thread is a right-hand, coarse UNC series with a Class 2B thread fit for consistent engagement. Key dimensions include a 3" width across flats and a 1 3/32" height. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and safe for use in regulated markets.
