- Environmental compliance meeting REACH and RoHS 3 standards for safe industrial usage
Professional Applications & Engineering Value
This zinc-plated steel flange lock nut delivers critical vibration resistance where conventional fasteners fail. The serrated locking mechanism beneath the 3/4" flange creates permanent friction against mating surfaces, eliminating the need for additional locking components in industrial machinery, automotive assemblies, and structural frameworks. Engineered with UNC coarse threads and Class 2B thread fit, it maintains precise tolerances while accommodating minor material variations. The external hex drive enables high-torque installation using standard tools, while the zinc plating provides essential corrosion protection for outdoor equipment and manufacturing environments where chemical exposure occurs.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2B thread fit and UNC 3/8"-16 coarse threading. Features a 3/4" flange diameter with 0.1" thickness and standard hex profile (9/16" width, 11/32" height). Compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations, ensuring safe usage across industrial sectors. Right-hand thread direction with external hex drive accommodates standard installation tools and procedures.
