Metric Class 10.9 All Metal Locknut Din 980V Zinc/Wax Cr3 Plating

When your application demands maximum strength and uncompromising security, the Metric Class 10.9 all metal locknut built to DIN 980V standards with Zinc/Wax Cr3 plating is the fastening solution you can trust. Designed with a prevailing torque feature, this locknut uses a deformed thread at the top to create a vibration-resistant lock—without any nylon inserts—making it ideal for high-temperature, high-load, and high-vibration conditions.

Manufactured from Class 10.9 alloy steel, this locknut offers excellent mechanical strength, durability, and resistance to shear or fatigue under stress. These properties make it a staple in automotive suspension systems, structural steel builds, power generation assemblies, and heavy industrial equipment where fastener failure is not an option.

The Zinc/Wax Cr3 plating brings additional benefits—offering strong corrosion resistance with a trivalent chromium (Cr3) coating that’s RoHS-compliant and eco-friendly. The dry wax lubricant layer reduces friction during tightening, minimizing galling and ensuring consistent clamp loads. That means better performance and faster, more reliable installations—whether in the factory or field.
