I seriously doubt it. That info keeps many companies in business. For screws and such. thread pitch gauges, and you need a commercial/industrial set. And that might not even be enough. The firearms industry has always used oddball crap.
I just went through this with the drill and tap for the 416 front sight. The neighbor has been a machinist all his life, Told him the front screw was 6-48..Said we should get a carbide, he'd order one...."NOPE", says I..... " I can get one from MSG" says he...."knock yerself out" says I....30 minutes later, he proceeds to tell me the thread pitch I told him is wrong. Proved him wrong, and he hardly accepted it even then. Called later to see if I screwed up. Nope.
To this day, screws on firearms can be a bastard. Be careful with the head type on scope bases. They are changing head contours, and it can bite you in the ass. Had to search for hours to find a double square shouldered screw for the front sight I had. Open sights use REALLY oddball heads.
