@zipper777: "I tried to Google this but I couldn't find what I was looking for. I'm 
looking for a tool that will let me check what kind of screw hole something 
is. For example, I have a threaded hole on a piece of equipment, what I want 
to know is what size screw would fit in there. I'm not looking for depth, 
just for the thread pitch and the size of the screw. I could just buy a 
bunch of screws of different sizes and keep them on a string, but I was just 
curious if there was already some clever tool that would make this process a 
little more elegant. Any help would be appreciated. Thanks

    @tomiller: " There are thread pitch gauges that you can use to measure the pitch and use
a vernier to measure the diameter, but they aren't a practical solution on
any female thread under about 12 mm.They work ok on smaller male threads
though.

1. Go to the hardware store and get an assortment of bolts, one each of
likely sizes.
2. Put them somewhere all together, keep them together, and remember where
you put the box (or bandaid can or whatever).
3. Next time you need to know, look at it closely and GUESS. Then go test
it and iterate.
By forcing yourself to take your best guess, you will rapidly learn the
sizes. If you're having a little trouble seeing up close, get some safety
glasses with a reading inset.
Time goes by, soon you don't need the little box anymore. If you're cheap,
you saved the receipt and then return the bolts. :-)

    @zipper777: "Ahh thank you, that is exactly what I needed. Glad to see someone thought of 
it. Thanks again.

I had a similar problem with a threaded hole in a camera. The hole was 
less than 2mm diam, but despite trying all the flavours of metric, 
imperial and BA that I had, none of the screws would fit.  In the end I 
took a piece of copper rod that appeared to be the right size, filed 
four flats on it to make a square section rod, and screwed it into the 
hole. Being soft and with sharp edges, the threaded hole deformed the 
rod to form a thread on it which could then be measured properly. It was 
a thread I'd never heard of, but I managed to get one.
