Insulation Self Locking Washers can be classified according to different criteria:

1. Classified by material:

-Metal material: mainly made of high-strength steel, stainless steel and other metal materials, with insulation coating on the surface.

-Non metallic material: Made of non-metallic materials such as nylon and polytetrafluoroethylene (PTFE), it has better insulation performance.

2. Classified by self-locking mechanism:

-Serrated self-locking washer: The self-locking mechanism is serrated and relies on the frictional force between teeth to achieve self-locking.

-Wave shaped self-locking washer: The self-locking mechanism is wave shaped and achieves self-locking through the frictional force between the peaks and valleys.

3. Classified by purpose:

-Universal Insulation Self Locking Washers: suitable for fastening and insulation of general mechanical and electrical equipment.

-Specialized Insulation Self Locking Washers: designed for specific industries or application scenarios, such as high-voltage electrical appliances, rail transit, and other fields with specialized gaskets.

4. Classified by size and specifications:

-Standard specifications: Common sizes and specifications that comply with international or national standards.

-Customized specifications: Special sizes and specifications customized according to specific customer needs.

Through these classifications, users can choose the most suitable Insulation Self Locking Washers according to their actual needs to meet the needs of different application scenarios.
