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.

Exactly as described by seller. Good value for the money. Works as it should.

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

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

I’d never used one of these in the past but had a stripped oil drain plug. Worked great and super easy. Would recommend to anyone.

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.

I was in a very difficult position with trying to remove a bolt that was stuck, in a very cramped position, and was stripped to the point to where it was completely rounded. I couldn't get any pliers or vice-grips in there to get get a good hold of the bolt so I turned to these bad boys. I had never used a bolt extractor set before so I was not sure if it was going to work or not. I was able to quickly figure out which size I need and placed it on the bolt (was barely able to get it into position due to lack of space). As I turn the bolt extractor I felt it biting into the bolt, and they are engineered to bite into the bolt while turning it counter clock-wise. I then used a breaker bar to finally get that stubborn bolt loose. It was easy to get the bolt out of the extractor afterwards. This kit saved me a lot of headaches and time. Now that I have this kit in my arsenal I no longer fear stripping bolts because they will meet their end at the hands of these extractors.All in all, these were designed very well and are easy to use. The price was very affordable and I see getting a lot of use out of them in the future.

great kit here removed broken stud with in minutes after receiving item.had a broken exhaust manifold stud that was very short i hammed the bit to what was left on the stud and zipped it right out first try.
