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.

18-8 Stainless Steel—The choice for wet and outdoor areas because it resists rust. However, it will corrode or pit when exposed to salt water and chemicals.

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.

Finish-Your-Own Washers

Punch a hole in these washers to create a custom inner diameter for uncommon screw sizes. Washers take the pressure off screws and nut to protect your mounting surface.

Stainless Steel About Stainless Steel

18-8 Stainless Steel—The choice for wet and outdoor environments, these washers resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.

Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these washers won't degrade when exposed to harsh weather, salt water, and most chemicals.

Material Certificate—Washers include a report with a traceable lot number.
