Washers, Collars

Washers are parts used for screw tightening and spacers, and are also called washers. When seated on a screw, the seat area is increased, so it is used to prevent loosening. Also, tightening screws made of soft material such as aluminum, resin, etc. has the effect of preventing the sinking of the seat surface. The size and shape of washers used for screws and bolts are determined by JIS. The collar is a cylindrical spacer that is inserted into the end of the shaft and used for positioning. Washers with shorter collar lengths have no size or shape specifications, and their names change depending on the purpose of use. MISUMI has approximately 30,000 items, and we ship as little as one item with free shipping. Washers and collars can be selected from metal, non-metal, and other materials depending on the material, and they can be used according to various applications such as shapes, such as straight, flanged, counterbore, inner and outer diameter sizes, etc.
