RS PRO Steel Bright Zinc External Tooth Locking Washer M5 DIN 6797A 276-875

The RS PRO 276-875 Steel Bright Zinc External Tooth Locking Washer is a precision-engineered fastening solution designed for demanding applications requiring enhanced vibration resistance and anti-loosening properties. Featuring a robust steel construction with bright zinc plating, this washer offers outstanding corrosion protection and mechanical strength for both indoor and outdoor assembly environments.

Designed to meet the stringent DIN 6797A standard, the washer incorporates an external tooth configuration, specifically intended to prevent rotational movement and loosening of large fastener heads. Its teeth grip into the mating surface and the fastener base, providing shakeproof security under dynamic loads and vibration.

With compatibility for M5 screws or bolts, the washer distributes the load efficiently, reducing the chance of fastener failure during repeated stress or movement. Its 10 mm external diameter and 5.3 mm internal diameter ensure a precise fit, while the 0.6 mm thickness delivers reliability without compromising space.

The bright zinc finish not only enhances resistance to oxidation and moisture, but also maintains the washer's surface integrity under harsh operating conditions. Manufactured to A2 grade specifications, this washer delivers robust mechanical performance across a wide spectrum of industrial, commercial, and automotive applications.

Typical use cases include machinery and equipment that are frequently subjected to vibration, such as industrial motors, domestic appliances like washers and dryers, and automotive assemblies. The locking action is particularly advantageous in environments where maintenance intervals are extended or access is limited.
