■ Shape: Resin, rubber washer
A resin or rubber round washer that is inserted between the seat of the bolt or nut and the part when tightening bolts and nuts.
Used for damage to the original material during fastening, electrical insulation, etc.
■Material: Silicone
Resin is lighter than metal material, with excellent corrosion resistance and no need to worry about corrosion.
It is also chemical resistant, insulated, and does not become magnetized. Therefore, it is used in a variety of fields such as semiconductor and automotive fields.
High heat resistance, good electrical properties (insulation, arc resistance, etc.) Inferior performance such as tearing, pulling, and friction.
■Surface treatment: fabric
Surface treatment/plating is untreated.
Therefore, corrosion resistance and appearance are the characteristics and color of the material itself.
