What is a good source to find floor plate and trigger guard screws?

CSMC/Galazan.

I checked, all they had was Parker and Fox screws

For what make and model gun are you looking to get replacement screws?

Gun Parts Corp. is always a good place to look, and if they don't have them, it's probably just a matter of time until they do. You can also try E-bay, Gunbroker, and Google used gun parts for a number of other sellers. There are usually some guys selling miscellaneous gun parts and screws at most gun shows too, but that can involve some serious looking, and good luck too, when their stock is a mess of loose unmarked parts in boxes. Of course, used screws may not be properly timed when installed in another gun, and if you are particular about that, it may be necessary to have them made by a gunsmith.

I forgot about these guys:

Parts like these require no export licence and can be sent overseas.
I use them regularly and there's a fast turnaround. Some parts that are listed as "out of stock" can sometimes be sourced if you can contact them and ask the question.

Thanks guys, I found a great site, but am having trouble with the measurements. So in the nature of learning, how would you measure an A1032 or other sizes compared to what you have in hand?

RARiddle,
Sometimes you have to resort to making a duplicate of the thread from cerrosafe and the female thread in the other part. The female thread should be cleaned and oiled first. If you make a small dam with whatever is easiest for you, you can have a war to unscrew the duplicate. If you can't get it out, or break it; you can melt it out with a heat gun on "low" setting, or maybe some hair dryers. Once you have the duplicate, you can measure the diameter and pitch in the normal way.
