Shims (washers) are thin plates made of steel, nylon or bronze. They are quite simple yet essential, since they ensure the stability of the pin they are put in. They also reduce the backlash between arm and bucket of an excavator to a minimum.

With almost 1.000 different kinds of shims, which differ in material, size and height, we offer the biggest stock on the market.

Shims catalogue


Steel shims are made of tempered steel, which guarantees a better resistance, grip and duration. They are straight, thus fixed, and smooth, thus it is possible to handle the safely, even without gloves.

We can produce custom shims (e.g. zinc-coated) according to your needs.


On stock we have bronze or plastic washers, which can also be custom made.
