How to Remove a Stuck Nut (without Stripping Threading)





Introduction: How to Remove a Stuck Nut (without Stripping Threading)

If you saw my Instructable on How to make a wooden 6" bench-vise, you'd know that I recently stumbled across a pretty big collection of threaded rods. The only problem was that some of them had hex-nuts that were stuck, and I wasn't able to un-screw them.

Now of course I could grab one end with my locking pliers, and twist the hex-nut off, but that would result in ruined threads...

This "Quickie Instructable" will show the method that I came up with. It's really simple, doesn't require any fancy tools like propane torches and impact drivers, works for all types of nuts, bolts, screws, threaded rods, and more...

You'll need 2 more hex-nuts, 2 locking pliers, a spray lubricant, a vise, and less than 5 minutes to do this.

Let's get started!

Step 1: Lubricate the Hex-nut

The nut is probably stuck because of rust, so spraying it with some kind of lubricant would help release it. I recommend either WD-40 or PTFE, but grease or vaseline might also work.

Step 2: Add 2 More Hex-nuts, & Tighten

I screwed on two hex-nuts on the other side of the threaded rod, and tightened them together with pliers. This needs to be tight, but there is no need to overtighten. See the pictures for more information.

Step 3: Clamp the Hex-nuts in a Vise, & Remove the Nut

I clamped both hex-nuts in my vise, as shown in picture 1. Now, guess what? I clamped my big locking pliers onto the nut, and turned. The more force you apply, the stronger the force which stops the hex-nuts that are clamped in the vise from moving. I used a vise, but you can also use locking pliers, which work just a well

Tadaa! You've removed the hex-nut. But wait... Almost done!

Step 4: Unscrew Both Hex-nuts

All you have to do now, is to unscrew the two hex-nuts that were screwed on in step 2. You can see the second picture to see how that's done.

Hooray! You've now got yourself a free threaded rod! All I have to do now is remove the rust, and build myself another wooden vise ;)

I'm trying to make this title have the best, and most accurate title... HELP!

"How to Unscrew a Nut that's Stuck on a Bolt (without ruining threads)" is a bit long. I'd like to shorten it, and make it better

If you were repairing something in your house, and failed at releasing a nut that's stuck on a bolt, what words would you type in Google's search bar if you wanted to find an answer? I would really appreciate it if you reply to this comment with those words. (Ex: "How to release a stuck nut", "How to remove bolt from screw")

This has a lot more to do with how to hold a threaded rod without destroying the threads than it has to do with removing a stuck nut. This is only ONE instance of a stuck nut. I found this instruct-able and was severely disappointed. A more responsible title would be "Securely holding a threaded rod". The only decent rust penetrating "oil" is Kroil. Also, when you clamp the locked nuts in the vice, ONLY clamp the one towards the nut you are trying to remove. If you notice in your picture, the flats on the two nuts are not aligned. When you clamp both, you can either loosen or overtighten the locking nuts. By holding the inside nut, it self tightens itself against the other nut.

I'm sorry to hear this isn't what you were looking for and you were disappointed, but what I did here is what the title/thumbnail says.

I've never heard of Kroil, but when I Google it, I see that it's also known as penetrating fluid/very low-viscosity oil. I'm pretty sure that that isn't the only one...

I'm not sure why you're saying that they aren't aligned. If you don't use a washer (as someone suggested), they need to be slightly not aligned. However... However... I do agree with what you said, by clamping the inside nut. Agreed!

Can you please tell me from what you were disappointed?
