|Why do you need to hacksaw through the tapped hole?

So the rod/bolt is held rigidly when held in the vice.

|Does the sheet remain flat?

It has to be several threads deep the ones we made was 1/8 thick sheet

The vice pressure stops the rod rotating,

Is your piece of sheet very narrow, and looking rather like a nut with
a cut through one side?
In which case why not just use a nut?
