Professional Applications & Engineering Value
This heavy-duty hex nut delivers critical engineering solutions for industrial assemblies requiring maximum reliability. The black-oxide steel construction provides superior corrosion protection in demanding environments like construction equipment, machinery frames, and structural connections. The extra wide profile significantly increases bearing surface area, preventing material deformation under high vibration loads and extreme tension. With 1 1/2"-6 UNC coarse threads and Class 2B thread fit, this fastener ensures rapid installation while maintaining precise engagement in heavy machinery, transportation equipment, and industrial infrastructure projects where vibration resistance and long-term performance are paramount.
Specification Summary & Compliance
Manufactured to ASTM A563 standards with ASTM Grade C strength classification. Features 1 1/2"-6 UNC coarse threads with Class 2B thread fit for optimal clearance and engagement. Dimensions include 2 3/8" width and 1 15/32" height. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe usage across global industrial markets.
