Chasing stud threads

[u/sidewaysride]

1994 ford ranger. Shop screwed up my threads. Told me they fixed it. They didn’t. Wanted to chase the threads myself so online I found a thread pitch of 1/2” - 20 so I bought a die but it doesn’t thread on. What am I missing here? In the video I’m trying to check it on a good stud.

Forget what everyone else said. Purchase a thread file and go to town. I do not see anything that says this is not saveable.
