subject says all... the "good" hardware store closed up shop. Do True
Value, Ace, etc. carry them, or am I reduced to ordering from
McMaster-Carr? see p/n 93482A691 at www.mcmaster.com for example. The
bracket for the closer has ripped off my screen/storm door again and
this is the only thing I can think of that might provide a permanent repair.

None of the big box places seem to carry them. Harbor Freight carries
them and a combo pop-rivit / rivit nut setter. MSC, McMaster, ENCO and
the like will have them as well.
