Hi,

I want to be able to bolt things down to my workbench easily using bolts
with plastic moulded "wheel" handles. I don't have access to the underside
of the bench because of the way it is made, so I'm not able to use pronged
tee's :

So, what I want is a small 22m^2 plate that I can recess into the bench and
screw down from the top, where the plate has a threaded hole in the middle,
maybe even a back nut or threaded sleeve behind it.

Does anything like this exist? If so what are they called and where would I
get some?

It's not an insurmountable problem, but if there is a "thing" that already
exists, so much the better...

Cheers
Chris
