Lock washer with nose DIN 432 M20 / 21.0

Product detailed description

The lock washer with an external nose according to DIN 432, ČSN 02 1753 and ISO 2342 is a specific type of washer designed to secure a joint against loosening. This washer is made of steel, which guarantees its high strength and resistance to mechanical stress. It is designed for use with threaded joints with a metric thread M20, while its internal diameter is 21.0 mm.

The washer is equipped with an external nose, which serves to secure the washer against rotation and thus the entire assembly. This structural element increases the reliability of the joint by preventing the nut or bolt from loosening spontaneously due to vibration or dynamic load. The nose of the washer is inserted into the corresponding hole or groove in the material being joined, thus achieving a firm hold.

Washers according to DIN 432 are often used in mechanical engineering, the automotive industry and other industries where it is necessary to ensure a reliable and permanent connection. Their use is particularly suitable in applications where joints are exposed to vibration or cyclic loading. Thanks to their design and material properties, they provide a high level of safety and reliability.
