Mitutoyo Test Indicator
Clamp holders, Attachments and Accessories


Made by Mitutoyo, specifically for their own brand of test indicator. Most of these attachments will also fit other manufacturers' models. If you would like to see Swiss made indicator attachments, which will also fit most Mitutoyo models, please refer to page 36.

If you are specifically looking for contact points, you will find them listed on page 21.

Why do we keep writing "most models?" Because Mitutoyo makes one unusual indicator called "Pocket Type." It has a tubular body and roughly (very roughly) resembles the Starrett Last Word indicator. It does not have any dovetails so the regular stems and attachments have no way of being attached. You will have to be quite specific when ordering attachments for these Pocket Type indicators.

To place an order: simply click on the linked part numbers below. Parts not shown, are not available from us at this time.


Mitutoyo stems, clamps and holders for test indicators with dovetails



The swivel clamp shown above attaches to the dovetails of all indicators which have dovetails. This includes Starrett, BesTest, Compac, Interapid, Fowler, and even generic Chinese indicators. There are two holes in the clamp, of different diameters, and the clamp is tightened with a single thumb screw.

Stem attachments with different diameters will fit any test indicator that has dovetails whether made by Mitutoyo or someone else. These come with a knurled nut which, when tightened, will firmly clamp the stem to the indicator. The usable length of the stem is 18 mm.

Holders specifically for Mitutoyo Pocket Type indicators


The universal holder for the pocket type indicators such as model 513-518 (and the older 513-118) screws into the end of the indicator. It is not designed for a dovetail. A ball joint allows it to swivel to a desired position.

  • spanner wrench (required to fasten holders onto body) 301336 ... $12.75


Mounting stems (shown in photo above) screw directly into the end of the indicator. They come in different diameters and allow for easy, rigid mounting in other holders and magnetic bases.

  • rigid mounting stem 3/8" Ø 102081 ... $18.05
