M14 Shim Washers DIN 988 in A2 Stainless Steel

Shim washers or shim rings are a type of washer used as part of an assembly in order to prevent machine components from moving axially, and are often secured with circlips or lock washers. Being manufactured in a range of thicknesses and to high tolerances, they are employed as spacers to fill gaps and create level surfaces in an assembly. These items allow for tighter and more precise alignment of machine parts, as well as being a load bearing surface. Shim washers should be located against smooth surfaces and not used where there is a step or chamfer, as there is a risk of the washer becoming deformed when used against an irregular surface.
