Shim Stock

Cut into custom shapes to create shims that suit your needs. With thickness tolerances as fine as a strand of hair, the shims will precisely align, space, and level components on dies, presses, and machinery.

You can stack multiple shims to achieve your exact thickness, but stacking more than four may cause them to shift. Remember, fewer shims are better, so a couple of thicker shims are more stable than a bunch of thin shims.

Bronze—The choice for marine environments, it won't rust or deteriorate from exposure to salt water. It offers better corrosion resistance than 316 stainless steel but isn't as strong.

Copper—A good conductor of heat, it’s often used to install heat sinks. As our softest metal, it prevents component damage but may not retain its shape as well as other metals.

Temper Rating—Choose half hard to create shims that you’ll need to bend or shape. Opt for full hard to make stronger shims that will maintain their shape under loads.

Shim Stock Assortments

When you don’t know the exact shim thickness you’ll need, keep shim stock in multiple thicknesses on hand so you always have the right one. Cut this shim stock into custom shapes to create shims that suit your needs. With thickness tolerances as fine as a strand of hair, the shims will precisely align, space, and level components on dies, presses, and machinery.
