Threaded part chucking technique - GIF

[Frank S]

Okay this is great. I'm definitely going to use this.

A 1/16" aluminum tig rod works real well for most bolt pitches the rod will bend around the bolt super easy and will deform into the treads better when chucking.
I generally use 4 nuts on a bolt instead. run all 3 onto the threads chuck upon 2 use the 3rd as the jam nut. When doing several bolts just run 1 nut all the way down. leave the 2 nuts chucked up loosen the jam nut and remove bolt you are ready for the next bolt almost like a collet
