I need to make thousands of fasteners consisting of 1/4" x 4" threaded
rod with a 20 degree bend in the center. The ends will each get a 1/4"
nylon-insert lock nut. I plan on doing the bend on a punch press. I'm
concerned about:

-What grade of All-thread so the rod doesn't crack at the bend?

-How to cut the rod? (parting die on punch press, bandsaw, cut-off
wheel in chop saw, etc)

-How to deburr so the nuts will start?

This is for a new product so I will be ramping up and might have to
change methods according to demand.
