D-Shaped ID Washers



D-Shaped or Spindle washers are made to be used with D-shaped shafts, rods, and mating parts. These washers are often utilized to modify spacing and alignment. The flat edge of the D-shaped hole prevents the washers from turning or rotating on the shaft in applications. D-shaped ID washers are commonly used in the automotive, aerospace, industrial, and many other industries where preventing movement in an assembly is essential.
