I have never tried the bending holes at least that's what I think they are for also.
The threaded bolt I have used a a hold down, I do not know if that is what it is for, but it works good.
Cut a piece of 3/4" or 1" rigid to fit between this bolt and the 'ceiling' (A beam, the metal decking of the above floor etc.) then tighten the bolt, it pushes the vice firmly to the floor. The bolt is off to the side enough to be out of the way.
Most times I do not do this, but occasionally I have and it keeps the vice from tipping when you have 10' of 2" GRC sticking out the back.

Bingo-the screw is a hold down, and the holes are for bending ridgid pipe or IMC. The two slots are for hanging tools like a reamer or a pipe threader handle.
I have several of my grandfathers tools including some original Stillson wrenches with the wooden handles. Old tools are a real favorite of mine and I travel around to farm auctions here in the summer whenever I get a chance.
