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.

Carbon Steel—Best for dry areas since moisture will cause it to rust.

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.

Tight-Tolerance Multipurpose Low-Carbon Steel Bars

Sometimes called flat stock, these bars have a thickness and width that are precision ground to a tight tolerance. They’re low-carbon steel, also known as mild steel, which is easy to machine, form, and weld. Use them for fabricating parts that don’t require high strength, such as fixture clamps and mounting plates. For added wear resistance, the surface can be hardened with heat treating.
