[ARC5] ARC-5 Lock-washers from McMaster-Carr

[D C _Mac_ Macdonald]

I think I bought some from Fastenall just up the road.  Lot of 100, IIRC.

K2GKK/5 in OKC, OK

They'll be close enough, though for purists they are about .010" too large in outer diameter, and don't clinch around the screw like the originals.  The OD isn't a problem if you use the McM-C 3/48 screws, because they are about .010" larger in head diameter than the originals as well, but the loosey goosey washer ID means that they usually get slightly eccentric with the screw head when you fasten the screw down.  There's not much you can do about the ID problem.  Still, they are better than nothing.

I just contacted one of the better fastener houses.  Min quantity typically 10,000 pieces.  Prices very good but.... They recommended McMaster-Carr for smaller quantities of #3-48 hardware.  I checked with Small Parts again but the #3-48 part numbers copied off the bags on hand from previously ordered stuff is no longer available, it appears.  Too bad.  But, your recommendation to go to M/C looks to be the best route, now.
