This shim is a flat sheet used to fill gaps and set precise spacing between mating surfaces during alignment work. Symbol SHIMS-100-040-CT-100X100X0.40 corresponds to dimensions of 100 x 100 mm and a thickness of 0.40 mm, with a net mass of 25.0 g. The flat, uniform geometry allows it to be stacked or trimmed to build up the exact gap needed under a base, foot, or mounting surface. Because thickness is fixed and consistent across the sheet, it supports repeatable adjustments when leveling components or correcting height differences during installation.
