DIN6796 Conical Spring Washers

DIN 6976 Conical Spring Washers use their inclined, elastic shape to generate axial spring force when compressed in a bolted joint. This spring action helps maintain clamping pressure when the assembly experiences small changes in length caused by vibration, thermal expansion, settling, or component tolerances.

Compared with flat washers, the conical profile provides a controlled spring effect while requiring little additional installation space. The washers can be used individually or in suitable arrangements when a higher spring effect or different load characteristics are required. DIN 6976 Conical Spring Washers are suitable for machinery, industrial equipment, bolted joints, mounting assemblies, electrical equipment, and other applications where maintaining bolt preload and compensating for dimensional changes are important. They can be supplied in different materials, sizes, and surface finishes according to the application requirements.

Specification:

DIN 6976 Conical Spring Washers are manufactured from spring steel or stainless steel to provide controlled elastic force in bolted connections. The conical shape allows the washer to deflect under axial compression and generate spring force, helping maintain joint preload when small dimensional changes occur during service. The spring characteristics depend on the washer diameter, material thickness, free height, material properties, and working deflection. Carbon and spring steel versions can be heat treated to achieve the required hardness and elastic performance, while stainless steel options are available for applications requiring improved corrosion resistance. Dimensions, spring force, and tolerances can be supplied according to the applicable standard and customer requirements.

Dimension Chart of DIN6796 Conical Spring Washers:

The dimension chart provides the main measurements for selecting a DIN 6976 Conical Spring Washer. It covers the washer diameter, material thickness, free height, and other dimensional features that determine the available spring movement and installation space. The correct washer size should be selected according to the fastener size, available space, required spring effect, and expected compression. Please refer to the individual size data for exact dimensions and tolerances.

Note: Spring force varies with washer size, material properties, and working deflection. Load values should be evaluated together with the required compression rather than by washer size alone.
