Most tap and die sets include a thread pitch feeler gauge. Measure the OD of the threads and the thread pitch, then order screws in the correct length with those characteristics. If you don't have the feelers for thread pitch, most hardware stores have a set of threaded metal holes that you can thread bolts or screws into to get the correct thread pitch and diameter rather than trying to eyeball them and guess. Be aware that thread pitches are different for metric and US screws, and that due to manufacturing variability and tolerances, screws that technically have the same thread pitch may still fit slightly tight or loose. The 64 probably uses screws made to US specs rather than metric.

For some of C64-IIs they didn't even use screws at all. As for the boards, it also depended on the version and manufacturing site but at least AFAIR the diameter was constant. > > The best bet is to take an original one to the nearest hardware store and see what they have. Look for the smallest sheetmetal screws they have and work up from there. If it's a small store, maybe bring the C64 and try them out right there. > > The ones I bought work well as replacements for my original breadbox and C64Cs that are (now: were) missing screws. > > And yes, I have a C64C from the end of 1990 that only uses screws for the board, everything else uses plastic clips, including the keyboard mount.
