Professional Applications & Engineering Value

This Grade 5 zinc-plated steel hex nut delivers critical performance in demanding applications where reverse-thread security is paramount. The left-hand UNC coarse thread design prevents loosening in rotating equipment subject to counter-clockwise forces, while the zinc plating provides essential corrosion protection in manufacturing, construction, and heavy machinery environments. With its Class 2B thread fit and external hex drive, this nut ensures consistent clamping force and straightforward installation using standard tools. Engineers specify this component for conveyor systems, power transmission equipment, and industrial machinery where vibration resistance and directional thread security are operational necessities.

Specification Summary & Compliance

Manufactured to UNC coarse thread standards with Class 2B thread fit for precision engagement. Dimensions include 3/4"-10 thread size, 1-1/8" width, and 41/64" height. This Grade 5 hex nut complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial compliance standards are met for global distribution and use.
