Without going into a lot of detail, I have to remove about 200 stainless

Does anyone have a better idea than my vice grip?

Well, for a deck you'd be comfortable standing on, I'd get some
iron pipe and fit a T handle to one end, and weld a T-10 shank,
or the shank of a screwdriver that accepts T-10 bits, to the
other end. If you don't have welders, epoxy and wood
can make a suitable handle.

Yeah, it's a bit of work, but hunched over at floor level
is not my idea of quality time...
