A Shim is a thin piece or layer of material that is inserted between two objects or components. Shims can be inserted to bridge these gaps and achieve the desired fit or clearance between parts. Common shim materials include metal steel, aluminum, brass, plastics, rubber, and composite materials. Attributes:• Helps reduce unwanted vibrations• Distribute loads evenly between mating surfaces, avoiding localized stress concentrationsApplications:A Shim is used to provide support to achieve the desired fit and provide a larger surface area to spread the load and prevent damage to the surface.
