Thanks Pete and everyone, really fantastic input.
Using the new bolt info, it's refined a little more:

I can't find anything suitable on MMC
(https://www.mcmaster.com/#countersunk-head-machine-screws/=1b0p4yz )
so Chuck's probably right, machine them up. Maybe start from a long 5/16" shank
hex-head bolt and put the
countersink and 1/4-20 thread on.
Thanks for the drawing for the kickplate. I'm assuming the plate goes on after the
feet have been placed
on the rack, and the #10 screws hold it all together. I'm guessing the kickplate is 16
guage sheetmetal..?

Except the proper screws are countersink head, not mushroom, because
mushroom heads would prevent the kickplate being fitted (and the shank
is 5/16" - only the end is threaded 1/4-20). No, as would be obvious to anyone looking
carefully at the photo (or the
real thing!), it's 1/4" x 20 UNC.? I really must learn to think before
putting finger to keyboard.
If it's "quarter-twenty", that's a size shared by many refrigerators
and
other heavy household appliances. I think I even have a few of those
mushroom-headed screws salvaged from one.
