About Shims and Shim Stock
Shims and shim stock are used to fill in a space between two mating surfaces or components. Shim stock consists of thin pieces of metal, plastic or other material used to fill space between objects for support, leveling, or adjustment of fit. Shims and shim stock can also act as electrical insulation and seal joints. Valve shims are used to adjust valve spring pressure. Laminated shims allow layers can be peeled away to produce a shim of required thickness. A carpenter or cabinet-maker can use small pieces of wood (shims) to fill gaps between larger pieces. Bearing shims are used for bearing adjustment. A shim kit contains shims of varying thicknesses and sizes arranged in a carrying case with labels for easy selection of the right size shim.
