Professional Applications & Engineering Value
Engineered for industrial fastening applications where vibration resistance and long-term reliability are critical, this 3/8"-16 UNC hex nut delivers exceptional performance in machinery, structural assemblies, and equipment manufacturing. The zinc-plated steel construction provides a durable barrier against corrosion while maintaining consistent thread engagement through the Class 2B thread fit. The extra wide profile significantly increases wrench contact surface, allowing higher torque application without damaging the fastener - particularly valuable in maintenance scenarios where repeated adjustments are necessary. With coarse thread spacing and right-hand threading, installation speed is maximized while reducing the risk of cross-threading during assembly operations.
Specification Summary & Compliance
This inch system hex nut features precise 3/8"-16 UNC coarse threading with Class 2B thread fit tolerance per ASME B18.2.2 manufacturing standards. Dimensions include 11/16" width and 23/64" height for consistent performance across applications. The product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe usage in industrial settings worldwide.
