The two hold downs thread properly both of the handles on them are a little bit misshapen, but nothing a bit of heat and tapping with a hammer can't fix. I think that the base was lightly tack welded to something at some point in its life because the very bottom fronts of all of the feet are missing a little bit of material as if weld bead was knocked off of it.The base sits flat and this is just a cosmetic thing. Nice set for someone who got one of these without a swivel base and needs one.
