Topec Stripped Bolt Extractor Kit, 18-Piece Bolt Extractor Socket Set, 3/8" Drive Rounded Nut Remover Set for Broken, Rusted Fasteners

UPDATE: I had to repurchase these because I cannot find most of my sockets. The reason I rebought these is because I went to AutoZone because they had a different brand, but I thought they would work. More like hoped, then knew they would. Sure enough the teeth completely stripped on the first try. China's finest garbage. So, I decided to rebuy these given my previous success as described below. And with a little bit of "shocking" the threads with a metal impactor, and these amazing sockets, they came out. I had three that were already stripped from using a 3/8 socket. These have special teeth on them. So, the tighter you torque the bolt, the more grip. I was able to get out all the bolts with these. Love these sockets. I tried other brands that just failed. Head bolts are the toughest bolts you will ever have to take out of a car besides rusted exhaust. Get these before you start your project. I wish I would have purchased this item sooner before buying other kits and trying my other bolt out kits. This worked great. I had to get out a stuck head bolt from my engine. OF COURSE.....the last one. It was so stripped I was out of options. That is till I give these 'men' a try. I wanted something with grip that was not going to just stripping the bold more. So these puppies arrived. And after having to pound the socket on the bold and some muscle...it came right out. What makes these so good is their quality to take a pounding. The most important is the teeth. The more you turn the bolt the more the teeth dig into the bolt. They are super short strong edges. This was one of the best I have ever used. I wish they would create a big 100 piece set or something. Like for those 4 mm bolts and those large 20 mm bolts. Wink wink!!

I needed these for a bolt on my transmission. The fluid level bolt was rounded off by the mechanic when he checked it last time and I could not get it out. I looked at many bolt removers and after reading the reviews I decided on these. These are made of excellent quality steel, and I was able to get the bolt out Pronto. No slip and fit in a really tight place. The socket wrench on the 11mm was compatible for a 3/8" drive wrench and fit with no slop. Highly impressed and glad I went with this branded set. !00% satisfied.

These worked great! I had a stuck 15/16 nut on my mower blades that was resistant to everything except blowing it off with a hand grenade. I used just a half second spray of penetrating oil, then a quick burst with my impact wrench using this extraction bit and that nut came right off. I should probably note that the nut was completely rounded smooth by the time I decided to order this kit. I could have saved so much time getting this first. Super easy to use. Socket size fit perfectly and removing the bit afterward was super easy. Not a single bit of damage to the bit either, I was expecting almost a one use product, but you can't even tell I used it.

I used the 14mm socket to break loose stripped and rusted brake caliper bolts. I had to hammer on the socket to the bolt then had to hammer the ratchet to break the bolts loose. I was very happy to see that the socket worked as advertised and both bolts came out on first try.

Easy to use be sure to use a hammer

Work excellent, used them to take out oxygen sensors

This easy-to-use set got loose a nut in a couple of minutes which I had spent a long time fighting with other tools. Good value for money. It is a nicely packaged set which is a great addition to my set of tools for working on a car kept in a rust-inducing climate. I expect these sockets to save time and trouble in other situations too.

Did exactly as advertised. I had a rounded bolt. A couple hits with the impact to get it started, then a couple more with a hammer, and bam, out came a stuck bolt. Works well and works as advertised. 10/10 would recommend.

Its seems good quality and good box there is little damaged in out side box but its acceptable

Worked perfect

Nothing beats real user reviews and this product had the best reviews. Upon receiving it, I looked it over and it seemed to be well made and of good quality and well designed. That even goes for the case! As a former mechanic, I was extremely dubious but the reviews were good. I had one bolt that was destroyed by some incompetent amateur. It was impossible to remove without using oxy or welding something to it. See pic! There was enough of a head left. Could this tool actually work??? If it didn't shift the first time round...it's all over. Back to plan B. I assembled the correct size socket, extension and ratchet and...boom! Success. It gripped without slipping and the bolt was removed. Amazing and definitively a worthwhile purchase. Highly recommended.

Good quality.
