Washer with internal teeth DIN 6797I M2 / 2.2 zinc

Product detailed description

The washer with internal teeth according to DIN 6797I, with a size of M2 and an outer diameter of 2.2 mm, is made of galvanized spring steel. This type of washer is designed to secure a joint against loosening due to vibration or dynamic loading. The internal teeth of the washer ensure a firm grip on the surface of the bolt or nut, thereby increasing friction and preventing the joint from loosening spontaneously.

Washers with internal teeth are often used in applications where it is necessary to ensure high reliability of the joint, for example in the automotive industry, mechanical engineering or electrical engineering. The zinc plating provides additional protection against corrosion, thus extending the service life of the component even in difficult operating conditions.

The washer with external teeth according to the ČSN 021744 and DIN 6797A standards has similar properties, but its teeth are oriented outwards, which allows for better adhesion to the surface of the material to which it is attached. This type of washer is suitable for applications where it is necessary to ensure a firm connection on smooth or softer surfaces.

Both types of washers are part of the fastening material, which is essential for reliable and safe assemblies in various industrial sectors. The choice between internal and external teeth depends on the specific requirements for the connection and the characteristics of the materials being joined.
