Suitable for small dial test indicator (like KHCRAFT dial test indicator, please visit our store www.amazon.com/khcraft to see it) and even hold 2 test indicators at the same time. But this mini holder is not so suitable for normal dial indicator 0-1", which is too heavy, though you could put on our stand with the hole 3/8".

2 ways to hold test indicators: with 3/8" stem or dovetail
