There are different kinds, some smallish ones use a cheap mandrel and a
pop-rivet tool to set. I have set larger aluminum ones by threading in a
bolt with a nut and flat washer, then tightening the nut down against the
insert (while holding the head of the bolt). Don't know if that would work
for large steel ones, but I don't see why not.
