Inch Dial Indicator

Group 1 Small dial Ø 40 mm model equivalents

This page is designed to help you find equivalents to dial indicators with small dial faces which you might own or want to replace. It will show the new models when others have become obsolete. It can also help you find better quality equivalents or—vice versa—cheaper alternatives.

We have taken the major parameters into account: the range, the graduations, the dial diameter and the stem diameter.

We've divided the models into groups of those with 8 mm diameter stems, and those with 3/8" diameter stems. Some indicators ship with a lug back, others have flat backs and lug backs need to be ordered separately. There will of course be some variation from one manufacturer to another.

Notes

Models shown with links are featured elsewhere on these pages. Please don't hesitate to check them out!

Most indicators are available with flat or lug backs. We have not included all the options in this list. If an indicator is listed with a flat back, it just means that you'll have to order a lug back separately. The opposite applies to indicators with flat backs. Whenever you buy a new indicator, always specify what kind of back you'd like.

Tthere is some variation in the bezel diameter among manufacturers but they are approximately 1-1/2 inches. That's why they're grouped under the "Size 1" category.

It is possible to turn an 8 mm stem into a 3/8" stem by using an adapter sleeve. This will not work in the reverse direction. There is no way a 3/8" stem will fit into an 8 mm hole.
