What size are those teeny-tiny screws that mount the back onto a 1" travel, dial indicator?
The back is barely hanging on by its last screw, 3 are missing. :(
I need to scare-up some screws, asap, but don't have any accurate way of measuring the holes.

You might consider removing the last screw and measuring it.
That information and the chart recently published in Machinist's workshop, may give you a clue.

Telling us the brand of indicator might help a little.

Taking the last screw and measuring it would help more, assuming it fits in the other 3 holes.

Take a round toothpick or sliver of wood and whittle it down with a razor knife until it will almost fit.Dab it with some super glue thread it into the hole and wait a couple minutes.Unscrew it and measure it.

I have seen 0-80 and 1-96 on US made tools and M2x.4 and M2.5x.45 if that hekps you any.

That's what I was afraid of... Nothing's standard.
Could be 0-80, 1-96, M2, M2.5 GGGRRRR.
I wish I had thread gages that small.

I agree, it's probably a GGGRRRR

Mike it. Cheat on about 0.002" and hit the charts. Tricky part if finding fillester head screws. Long Island Indictor seems to be the default source.

Maybe a screw from an eyeglass repair kit would fit.

Stick a 40tpi gauge up to it,if it spans two pitches at a time and comes in even it's 80tpi same principal works for the rest.

If all else fails and you have an ACE hardware local go check them out.Ours stocks flathead machine screws and Allen screws down to 0-80.It's only an indicator,it's most likely chromed brass or soft SS,drill and tap that sucker to fit what you can find.Just do all the holes to keep it neat,your a Machinist,machine it!:)

so, does the hole have to be oiled, or how dcan you unscrew it?

You can if you want,most times typical generic super glue doesn't stick to metal very well and most of it will be soaked up by the wood anyway.

Longisland Indicator can tell you and may even help, for a price of course.

This outfit http://www.morris01550.com/products.htm sell inch and metric miniature screws that of excellent quality. The stainless steel screws can be bought in quantity 1 if desired. They aren't cheap, but they are very well made.
