Professional Applications & Engineering Value
Engineered for demanding industrial applications, these 3/8"-16 UNC hex nuts deliver critical performance advantages through their hot-dipped galvanized steel construction and extra wide profile. The heavy-duty ASTM Grade 2H rating provides exceptional clamping force retention in structural assemblies, bridge construction, and heavy machinery where vibration resistance is paramount. The coarse thread design enables rapid installation in field conditions while the Class 2B thread fit maintains precise tolerance control, preventing loosening in high-stress environments. The zinc coating offers superior protection against rust and chemical exposure, making these nuts ideal for outdoor infrastructure, marine equipment, and industrial plants where corrosion failure is a primary concern.
Specification Summary & Compliance
This heavy-duty hex nut features 3/8"-16 UNC coarse threads with Class 2B thread fit tolerance, measuring 11/16" width and 23/64" height. Manufactured to ASTM A194 specifications with ASTM Grade 2H strength classification. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards for industrial fastener applications.
