Flexible washer under cylinder head DIN 7980 M8 / 8.1

Product detailed description

The DIN 7980 cylinder head spring washer is a special fastening component designed to ensure reliable fastening of cylinder head screws. This washer is made of spring steel, which gives it high resistance to dynamic loads and vibrations. Its square cross-section design allows for effective pressure distribution and increases friction between the fasteners, minimizing the risk of loosening the joint.

The washer has an outer diameter of 8.1 mm and is designed for use with bolts with a metric thread M8. The DIN 7980 standard, according to which this washer is manufactured, specifies precise dimensions and tolerances, which ensures compatibility with other standardized components. The use of this washer is suitable in applications where high reliability of the connection is required, such as mechanical equipment, the automotive industry or structures exposed to vibrations.

The spring washer under the cylinder head is categorized as a self-locking element, which means that its primary function is to prevent the bolt from loosening spontaneously. This type of washer is particularly suitable for applications where frequent load changes occur or where it is necessary to ensure long-term stability of the connection without the need for additional tightening.
