Screws for Vise Jaws

[Lookin4'67Galaxieconv]

I have an old Columbian vise I've been cleaning up and just painted today. I'd like to find some new slotted screws for the jaws to replace the originals.

Should any good Mom & Pop hardware store have these?

Or will I need to get them from a more specialized outlet?

The only problem you might run into is finding the proper shaped screw head.
