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

Metric Class 10.9 All Metal Locknuts – DIN 980V Performance for Extreme Conditions

When your application demands maximum strength, vibration resistance, and absolute reliability, the Metric Class 10.9 all metal locknut manufactured to DIN 980V with Zinc/Wax Cr3 plating delivers confidence under pressure. This high-performance fastener is engineered with a prevailing torque locking feature, created by a precisely deformed top thread that grips the mating bolt securely—without relying on nylon inserts that can soften or fail in extreme environments.

Built for High Load, High Heat, and High Vibration

Manufactured from Class 10.9 alloy steel, these all metal locknuts provide exceptional tensile strength, fatigue resistance, and durability. They are specifically designed for high-load and high-vibration applications where joint integrity is critical. Because the locking mechanism is entirely metal-to-metal, performance remains consistent in elevated temperatures and demanding operating conditions.

DIN 980V Standard for Proven Reliability

Compliance with the DIN 980V standard ensures dimensional accuracy, controlled locking torque, and repeatable performance. This makes Class 10.9 DIN 980V locknuts a trusted solution for OEM production, industrial maintenance, and structural assemblies where international standards and long-term reliability are essential.

Zinc/Wax Cr3 Plating Advantages

The Zinc/Wax Cr3 plating adds another layer of performance. The trivalent chromium zinc coating provides strong corrosion resistance in moderate to harsh environments, while the dry wax lubricant topcoat reduces friction during installation. This combination helps prevent thread galling, improves torque consistency, and allows for smoother, faster assembly. The Cr3 finish is also RoHS-compliant, offering an environmentally responsible alternative to traditional hexavalent chromium coatings.
