Metric Class 8.8 All Metal Locknut Din 980V Zinc/Wax Cr3 Plating

The Metric Class 8.8 all metal locknut manufactured to the DIN 980V standard with a Zinc/Wax Cr3 plating is engineered for high-strength, high-vibration environments where durability and resistance to loosening are critical. This prevailing torque locknut features a deformed top thread section, which creates a consistent friction fit on the bolt—even in high-temperature or high-load applications. No nylon inserts, no degradation over time—just reliable locking performance.

Crafted from Class 8.8 medium carbon steel, these locknuts provide superior tensile strength and are ideal for automotive assemblies, heavy equipment, construction frameworks, and machinery installations. The DIN 980V specification ensures dimensional accuracy and functional consistency, making these fasteners dependable for OEM and industrial use worldwide.

What sets this version apart is the advanced Zinc/Wax Cr3 plating. This trivalent chromium finish provides excellent corrosion resistance in moderate to harsh environments, while the dry film wax topcoat acts as a built-in lubricant, reducing friction during tightening and helping to prevent thread galling or seizing. It's RoHS-compliant, making it a safer, eco-conscious choice without sacrificing performance.
