Chair Casters and Furniture Casters with Metric Threaded Stems

Metric thread sizes are specified differently than USA thread sizes. USA sizes are specified using the nominal major diameter and the number of threads per inch.

To simplify metric thread callouts, the international (ISO) standard for metric threads eliminates the pitch callout on coarse threads. For example, the thread "M10" automatically means a coarse pitch, while any added pitch callout, such as M10x1.25, specifies a non-coarse pitch. This method of designation has the major benefit that average citizens do not need to memorize pitches just to identify a coarse thread.

All of our Metric Stem Casters have course threads and hence we could specify them as M6, M8 and M10. We have decided to use the entire callout so our customers know exactly what thread they are buying. This does not mean that they are fine threads. We are doing this to try to be exact.

Our theads are actually the following dimensions: M6 x 1.00 / M8 x 1.25 / M10 x 1.5.

All of the casters listed below have a metric stem option shown here in Red. Many caster resellers do not carry metric stems and many manufacturers do not even produce them. We have found casters of exceptional quality with the option for us to stock metric stems casters for you.

We believe that we have the finest collection of Chair Casters and Furniture Casters
available in one place on the internet!


Before you choose any of these casters, you should learn how to select the proper caster for your specific project. We'll teach you how to measure stems and to choose the correct caster to roll safely on your type of flooring. Click here or the Stop sign to go to School.
