So all that screw making and painting was not there to support computing, but rather was legacy manufacturing that computing took advantage of. They had a long legacy of mechanical engineering from the days of card punches and readers and teleprinters. Even into the 70s and 80s they were a major — perhaps by then the major — typewriter manufacturer. Typewriters were “business machines”. IBM’s original name was The Computing-Tabulating-Recording Company. They started out making cash registers and related products. Maybe a better way to see this is that during WWII they reconfigured their factories to make machine guns. Factories don’t look like that any more.
