So slip it over a stud and wind it out?

Wish I'd have one when I pulled down the 302. Like to never got some of the rusted studs out.

I have one for 5/16 studs, handy for removing the fan studs on water pumps on old domestic engines. I don't use it too much lately.

Those can be useful at times, but don't work all the time.

I have a set of those for metric sized studs, and have used it all of a few times.

I usually just weld a nut on, heat the flange cherry red, and the stud comes out by hand.
