What Are the Specifications for Belleville Washers?
belleville Washers possess a spring characteristic which can be used in a variety of functions including stacking applications for pressure. Our belleville washers are available in a wide range of outside diameters, thicknesses and inside diameters.

If we don’t have the outside diameter, inside diameter and thickness combination of the washers that you need, we’ll create a die and custom fabricate them for you in the quantity you require. We maintain dies for your next order of washers. As suppliers of custom washers for OEMs, we’re able to make exactly what you need within the tolerances you require.

What Are Plastic Washers Used For?
We offer flat plastic washers that are useful for many industries and applications. The uses of our flat plastic washers include plumbing, medical devices, furniture and automobiles.

The precision of our computerized systems can create plastic washers with very tight tolerances that are ideal for high-friction situations and protection against corrosion. Select from plastics including polyethylene, acetal, PTFE, PVC, nylon and polypropylene washers.

We stock plastic washers in standard and special sizes from with a variety of inside diameters and thicknesses. These washers are ideal for fastener distributors because they work in many applications to protect screws, nuts and bolts from the effects of corrosion, heat and friction.

Uses for Fender Washers
Our fender washers are used for standard applications including automobile repairs, industrial robots and other moving objects where spacing and protection are needed against undue wear between metal parts. The outer diameters of our fender washers range from 1.000 to 1.500 inches while the inner diameters range from 0.218 to 0.406 inches.

These washers are typically manufactured in both stainless steel and zinc plated steel. We can also custom fabricate fender washers in the material you require.

Uses of Shims
Our shims act as a support or level to protect washers or other applications against undue wear and tear. Shims can be manufactured out of numerous materials, such as plastics or metals, as well as in odd shapes.

Adjusting the clearance of the shim adds or decreases space between two parts. Our Shims range in thickness but are typically thinner washers with tight tolerances to meet spacing requirements.
