Model M Screws

I'll preface this by saying that I hate it when I do this: put something down in a good place, but then can't remember where that is. I'll also say I tried to search and there's only about 15 pages of results that contain the obvious words and Google, oddly, only has results for Models F.

Anyhow, does anyone have dimensions for all the screws in a Model M, including the grounding screw and nut? Specifically, this is an actual IBM 1391401 101-key BS made in 1990. It'd be extra tremendous if you have part numbers from McMaster or Amazon. I'm in the US. I do have some other Models M, but I have no idea how to measure a screw properly.

Thanks very much!

I have calipers and plenty of M screws, if you could post a picture of what exact screw you are wanting measurements for I'll try my best to get you some info.

Just the four case screws and the one on the inside of the case for grounding. Now I'll see if I can find my camera cable :{

And I now note that I'm missing the nut from my other Model M, so I need two nuts. Laugh all y'all want.

The measurement on the heads for the "silver" colored screws is 5.5 mm and the brass colored screw is 1/4". I don't know the length or what kind of screws these are.

Thanks for any assistance!
