How to Remove a Stuck Nut (without Stripping Threading)

▼ Learn More! ▼

In this video, I will show you how I unscrewed a nut that was stuck on a bolt without damaging the threads. I came across a few threaded rods that I wanted to keep for future projects, but some of them had hex-nuts that were stuck, and I wasn't able to un-screw them. I could have held easily removed it by holding onto the threaded rod with from one side with locking pliers, and and the nut with a wrench, but that would damage the threads, making that part of the threaded rod unusable.
I screwed on two hex-nuts on the other side of the threaded rod, and tightened them together with pliers, doing what is normally called a "jam nut". This needs to be tight, but there is no need to overtighten. I then clamped both of the hex-nuts in my vise Like I show in picture 2 (might be #3 for some mobile device users), held the nut tightly with locking pliers, and twisted it off. In the video, I actually held onto the nut with my vise, and used locking pliers to hold and twist the jammed nuts - but it doesn't really matter.
I then removed the jam nuts with pliers, and... Tadaa!

Sometimes stuck threads just won't come off. I was trying to unscrew a 1 1/2" brass trap adapter from a cast iron drain pipe tee. It wouldn't come off so I cut two slits in the male threaded piece, knocked out a chunk and squeezed the part to get it out.

You are a genius, my friend!
