Miriam,
The 1/2 x 10-28 means 1/2 inch length (of threads), size 10 diameter (at the threads) and 28 threads per inch.
The 10-28 screw fit both my 15-91 and the 201-2.

Ok here is a crappy pic of the two kinds of throat plate screws. The one on the left was the same length and held fine - the one on the right did not hold. [ATTACH=CONFIG]470472[/ATTACH] It may be that not only do the screws vary but the belt guards may vary as well.

Miriam,
I'll check my bobbin winder hoods/ beltguards and see if there are differences.

Cathy, I worked on another Singer 15 - I pulled it's half dead potted motor this morning - there is no way the throat plate screw goes in that one - I don't know if it has something crudding the hole or if it is a different thread pattern. It goes about a half turn- go figure.

gunsmithing suppliers are a good source for some "non-standard" screws with slots and undercut heafd. Are you sure those are #10? (OD about .192) for some reason I was thinking needle plate screws were smaller.
