Security Six grip screw

[AZ Pete]

Can someone tell me the thread size and pitch of the grip screw on a Security Six? Thank you in advance for the help.

I do know that the GP100 and the Security Six both take the same grip screw and the size is an 8 but the thread pitch I can't recall. It's either a 40 or 48 but I'm leaning towards 40.

Thanks Flash. I had tried every grip screw that I had and couldn't find a match, but my neighbors GP100 screw does. Great news since the GP100 parts are still available from Ruger and the Security Six don't seem to be.
