THINKWORK Bolt Extractor Kit, 18-Piece Nut Extractor Socket Set, 3/8" Drive Rounded Bolt Remover, Lug Nut Removal Tool for Damaged, Rusted, Rounded-Off, Stripped Fasteners

Excellent product. It has saved me at least twice so far. First time was removing a stripped oil pan drain bolt. The socket easily bit into the soft aluminum bolt and removed it with little effort. It was aluminum so not a big challenge.However, the 2nd time, it performed flawlessly. I had to remove the oil pan on my car but before I could do that, I had to drop the exhaust and the exhaust nuts were rusted on (as expected). They were so bad, it cracked the wall on my craftsman 5 point deep well socket. Tried a 2nd socket and it just stripped the nut. Went to the Thinkwork and it bit into that steel nut like Pit bull and held it firm. I put a LOT of torque on that nut using a breaker bar and it didn't want to budge but that socket held up to the stress with no issues. Again, it cracked my Craftsman socket, it was that much stress. After significant force, the nut finally broke free. When I got to the 2nd nut on the exhaust, it started to strip so I grabbed the socket again before the nut could strip and again, it took the stress without a problem and broke it free. By the 3rd nut, I didn't bother with my standard socket and went straight to the Thinkwork socket and once again it performed flawlessly. I would absolutely buy this set again. It's easily saved me hundreds...The quality of the materials seems solid and well made. The blown plastic container feels a little cheap but the sockets themselves are quite durable.

Good value and works well. I had a thin, rust corroded 10mm bolt (head was mangled and rusted), pouned on the 10mm extractor socket and spun it out effortlessly!

In the process of replacing the exhaust system on my car; I rounded off one of the nuts that held the exhaust to the catalyst converter. The nut was badly rounder. No matter how I tried I was unable to get the nut to turn. I was at a loss as to how I was going to get the nut off. I considered taking the car to a exhaust shop; but decider to try this product. It worked. After hammering the extractor in place, I took my impact wrench and the nut started loosening right away. Was able to remove nut with no difficult. Excellent product.

these are great and have worked many times since i purchased them... they just did work for why i got them read the description and it listed a size I desperately needed, once it arrived i discovered it did not have the size i needed. its worked well for other projects since then, no sense in returning tools

Very good for rounded damaged bolts. Tried other types of extractors but these were able to get a better grip. Other types just made my bolt rounder and more damaged. I recommend these curved type extractors . In my opinion they are the best ones for very round bolts.

Was able to free a bolt up that had completely been rounded off on a piece of heavy equipment. This bolt was very cinched up and rusted. Honestly didn’t think this was going to work but it did!!

I used this to remove (2) 13mm bolts securing a water-pump to an engine block. the bolts were just barely feasible from when I had the water pump replaced last year and I then I went on to remove the water pump myself stripped them out. I used a small hammer to pound on the smallest bit I could fit and the stripped bolts were removed with ease. I used this same kit to remove a 10mm bolt from the same water pump pulley, which is the whole reason I needed to remove the water pump entirely in the first place, because I couldn't remove the pully alone. this is a nice thing to have, I don't know about durability or long term use or other brands but this did the job and I'm glad I learned about it in the process

Works as it should. Handles well under stress.
