on a similar note ... I've seen reference to a special type of threaded
nut, used for quick fastening & unfastening on lengths of studding. The
idea is that with a bit of juicious ... tilting, pressing, or whatever,
you can slide the nut down most of the length of the studding. Then for
the last centimetre or so you tighten it up normally.

Quick nuts. They're just a long threaded nut with a clearance hole
drilled through them at a very slight angle. Pigs to make - you need a
very rigid drill press, a wedged jig and a stub drill.
