tandard:DIN6340
Description:
The DIN 6340 specification refers to a type of washer used in structural steel applications. These washers are typically made from structural steel and are designed to provide a larger bearing surface under the head of a bolt or nut. They help distribute the load and prevent damage to the underlying material.
The DIN 6340 washer is available in various sizes ranging from M6 to M30, which refers to the metric thread size of the corresponding bolt or nut. The "M" stands for metric, and the number after it indicates the diameter of the fastener in millimeters.
The washer can be plain or coated with Dacromet. Dacromet is a corrosion-resistant coating that provides protection against rust and other environmental factors. It is commonly used in applications where the fasteners may be exposed to moisture or harsh conditions.
In summary, the DIN 6340 washer is a structural steel washer available in sizes M6 to M30. It can be plain or coated with Dacromet for corrosion resistance.
