Professional Applications & Engineering Value

This heavy-duty hex nut with ASTM Grade 2H certification addresses critical engineering challenges in structural and mechanical applications. The extra-wide thin profile distributes clamping forces more effectively across larger surface areas, preventing stress concentration that can lead to joint failure. The coarse UNC threads provide superior resistance to vibration loosening in heavy machinery, construction equipment, and infrastructure projects. Manufactured from high-strength steel with precise Class 2B thread fit, this nut ensures reliable performance in bolted connections subject to dynamic loading and thermal cycling. The external hex drive design facilitates efficient installation and maintenance in confined spaces, while compliance with ASME B18.2.2 specifications guarantees interchangeability and consistent performance across industrial applications.

Specification Summary & Compliance

This hex nut features precision Class 2B thread fit with UNC coarse thread spacing and right-hand threading in sizes ranging from 2" to 4 1/2. Manufactured to ASME B18.2.2 specifications with dimensional accuracy including 3 1/8" width and 1 3/32" height. The product carries ASTM Grade 2H strength certification and demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for international industrial markets and regulated applications.
