Hi can someone please tell me what size a thread pitch my grip screws are on my Ruger SR 1911 thanks joe

Those threads are not standard, call Brownells, and call Ruger.

Standard screws fit in my SR 1911’s.

You can do it yourself easily with a calipers, and a magnifying glass if you need it. Pitch on a standard screw or bolt is nothing more than how many turns in 1". Mark 1" down the bolt, and count how many threads to the end. Say it is 40, your pitch is 40.
