Washer with external teeth DIN 6797A M3 / 3.2 zinc

Product detailed description

The washer with external teeth according to DIN 6797A, also known as ČSN 021744, is a specific type of lock washer designed for applications where it is necessary to ensure a reliable connection and prevent loosening of the bolted joint due to vibrations or dynamic loads. This washer is made of spring steel, which provides the necessary elasticity and resistance to mechanical stress.

The washer has external teeth, which means that the teeth are located on the outer circumference of the washer. This design increases the friction between the washer and the connected surface, thereby increasing the resistance to spontaneous loosening of the joint. Toothed washers are particularly suitable for applications where it is necessary to ensure a high level of connection security.

The dimensions of the washer are designed for screws with a metric thread M3, with an inner diameter of 3.2 mm. The surface treatment is made by galvanizing, which increases the corrosion resistance of the washer and extends its service life in harsh operating conditions.

This washer is part of a group of self-locking elements used in various industries, including mechanical engineering, automotive and electrical engineering. It is ideal for applications where it is necessary to ensure a strong and permanent connection without the risk of loosening.
