I bought a hole saw from Harbor Freight (yes, I know) and I chewed up
the set screw. I'm pretty sure it's a M5 x 1.0. Any kind of screw
head configuration would be OK, but I'd prefer anything but slotted so
that I can crank it down hard. But I can't find this screw size/pitch
in any configuration. I've looked at lowes, home depot, grainger,
mcmaster and fastenal with no luck.
