What is the recommended way to hold threaded galvanised steel rod in a
vise so that the thread is not damaged?
The rod needs to be cut with a hacksaw. Actually it will be cut in a
metal bandsaw, but it's the same question as the bandsaw also has a
vise.

I believe I have invented the best way, but I was wondering if there
was a "proper" way that a perfectionist engineer might use.

Take two nuts that are compatible with the thread and make a cut half
through them, so that when the threaded bar is in the vice, they grip
the threaded bar. Spin the bar into the thread and cut away. Have a stop
and when the stop is encountered the bar will be ready to cut

Alternatively. Use one nut whole and just cut the second one after
filing the first down a bit (this allows the first nut to act as a guide
and the second to act as the grip).

Or...

Cut through 2 nuts and glue them to the jaws of the vice and just
advance the threaded rod as required and cut.

HTH

BTW My consultation fee is a small matter of £50.00. But I ask that you
pay me at least £20,000 a week, for my suggestions. ;-)
