EEEKitMetal Nut Splitter Cracker, Manual Pressure Metal Nut Splitter Breaker Nut Remover Extractor Tool, 9-12mm, 12-16mm, 16-22mm

My SUV's rear windshield wiper broke and trying to replace it I pretty much destroyed the old wiper assembly because the embedded metal part that went over the motor's splined shaft wouldn't come off. I tried a gear puller but that was ineffective so I purchased this set of nut splitters. I put it over the "nut" and started to turn the bolt end. It started to shift a bit, so I unscrewed it, then started to screw it in but this time holding the body of the splitter firmly. The blade stopped moving and started digging into the metal. After only a few turns I heard a "crack" and the "nut" was loose. Success! I was then able to install the new wiper assembly. This product worked extremely well. Thank you for a quality product.

You need this if you work on vehicles ......!

Inferior quality tool. I used it once and the setscrew that holds the wedge in alignment sheared off and the pin on the wedge that turns in the screw is seized in the screw. Don't waste your money.

Good value for the money. Split the nut like a nut cracker should. Might have to bore out the smaller sizes to fit over the bolt head on the smaller sizes.

I had a nut on my sway bar end link in a bad position and just couldn't get an impact gun onto it. So nut splitter was an option to try. First attempt the pointy end of the splitter turned and kind of split the nut at an angle. Not a big deal as I could see it did split the nut partially. So I backed it off and straightened the splitter and adjusted the set screw. Had to go around the nut a few times to get it to break off into pieces that could come off the bolt.Then came the second nut that was in a more difficult position. And this time the splitter was not able to split the nut cleanly. And I could see the splitter getting duller each time as I went around the nut in different positions.And each time, the circle of the tool starting getting deformed and becoming ineffective. Then the set screw broke and I could no longer use the splitter. Then spent 6 hours with a dremel trying to finish the job.I would say that the nut splitter can work. But after a few uses it's pretty much done and becomes a throwaway item. Probably need several just to do one job.

I was trying to get the top nut off of my 2012 Prius rear shock absorber and it was not budging. I used the largest nut cracker on it and I had to use a socket with a breaker bar on the tool. I kept cranking it tighter not knowing which would break first, the tool or the nut, suddenly I herd something snap an I am glad to say it was the nut. Even then I had to unscrew the nut off of the shock absorber with a wrench while holding the shaft from turning with an allen key, it fought me the whole way but I got the nut removed and installed my new shock absorber. The other shock absorber while it too was difficult to loosen the nut, I was able to finally remove it with a wrench and allen key. I am glad I bought this tool, I sprayed the threads on the nut and shaft of the shock absorbers and then also the tool when I got it, prior to using it with WD-40.

Needed these to get the nuts off the shock absorber bolts on my daughter's car. Worked as expected and needed.

This set is just what we need to finish a project where nuts have been overtightened on threaded rods protruding from the ceiling. This is the only tool that will work. Seem to be very strong and will last a lifetime.
