These products are to be used in combination with bolts and nuts. Spreading the washer is effective for preventing the bolt from pulling through or loosening.
In general, washers can be divided into two types, metal or resin for isolation, water-resistance, and prevention of interference between fitting materials. Washers can be easily selected by searching for specifications suitable for the usage environment.
