Insulation Self Locking Washers are a special type of fastener that mainly consists of the following parts:

1. Gasket body: This is the main part of the gasket, usually made of high-strength steel or other alloy materials. The shape of the gasket body is usually circular, with a hole in the middle for passing through bolts or screws.

2. Insulation coating: In order to provide insulation performance, the surface of the gasket will be coated with a layer of insulation material. Common insulation materials include nylon, polytetrafluoroethylene (PTFE), and other plastic polymers. This insulation coating not only prevents current from passing through, but also has a corrosion-resistant effect.

3. Self locking mechanism: The key part of a self-locking washer is its self-locking mechanism, which is usually designed as a serrated or wavy protrusion or groove. These structures can generate additional friction when tightening bolts, thereby preventing washers from loosening.

4. Additional components: In some special types of Insulation Self Locking Washers, other additional components such as spring washers or anti loosening washers may also be included to enhance their anti loosening effect and stability.
