3/8"-16 Nut Locking Flanged YZ Grade 8

3/8"-16 Nut Locking Flanged YZ Grade 8

This 3/8"-16 flanged lock nut is manufactured from high-strength steel and finished with a yellow zinc coating for enhanced corrosion resistance in harsh environments. The integrated flange acts as a built-in washer to distribute the clamping load over a wider area, preventing damage to the mounting surface and reducing the risk of loosening under heavy vibration. It is commonly used across various systems in McNeilus, Terex, and Con-Tech concrete mixers where a secure, high-strength fastening solution is required. Replacing worn or rusted nuts with this Grade 8 hardware ensures reliable performance and structural integrity in demanding ready-mix operations.
