Hi Ferulebezel
Typewriters like early Harley Davidson motorcycles and Briggs & Stratton engines used a lot of now discontinued threads. On these machines, 1/4"-24 was regularly found on American built machines up until the 1960's, if not later. I had to buy a #10-36 threading tap for cleaning up threads in carburetors and #4-44 for some of the governor linkages.
Because many of these threads are now obsolete, I don't think you're going to have much luck finding modern replacements for the various screws. The only supplier of screws that might fit vintage typewriters would be a gun smithing supply company.
When working on these typewriters, a completely clean and clear work area is a must so any screw that gets dropped cannot find its way to the floor. As for the slotted screw heads, no other means of driving small screws had been invented when these machines were built, but for the exception of Robertson which never caught on in the USA as it was a pre World War One Canadian invention. Hope this gives you some food for thought,

We humans go through many computers in our lives, but in their lives, typewriters go through many of us.
In that way, they’re like violins, like ancestral swords. So I use mine with honor and treat them with respect.
I try to leave them in better condition than I met them. I am not their first user, nor will I be their last.
