Frequent Questions & Answers
What are shims used for?
What is the difference between a shim and a washer?
They are similar, but shims come in fine thickness steps for precise spacing, while washers mainly spread load under a screw head or nut.
What shim thicknesses should I keep?
A range from around 0.1 mm upward covers most setup jobs. Assortment packs are a convenient way to have every thickness on hand.
