13+1 Piece Impact Bolt & Nut Remover Set, 3/8" Drive Bolt Extractor Socket Set, 8mm-19mm Stripped Lug Nut Remover, Twist Socket for Damaged, Rusted, Rounded Fasteners

I've used several brands of EZ Outs and bolt extractors. I find that this spiral flute design works best for me. I like that this sets good variety of sizes, the 9mm was perfect for a well rounded off 10mm bolt on the intake of a 2006 Titan. Hammered on and bit in, turned out the stuck bolt with no slipping at all. After work, inspection showed no wear on the flutes. I have a lot of high-end tools, but I bought this set on a recommendation I trusted. I was kinda shocked at the quality. Good extractors.

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.

Work well

Previous owner had completely rounded off a brake caliper bolt on my daughter-in-law's 1991 Miata. Tried everything (short of fire) before ordering this kit and nothing worked. Even with limited space, this was able to bite onto the mangled hardware and (with a LOT of effort) extract the bolt. No noticable damage to the extractor either. Cannot recommend highly enough.

Worked great to remove a bolt that was stripped.

Saved my engine

You don't need them untill you need them...they have a good bite on bolts

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

Working on a 2002 Subaru with tons of rust, I was trying like mad to get the rear caliper bracket bolts off and they were horrible! I bought this kit and it took maybe 15 minutes and the job was done. These things far exceeded my expectations. For a home gamer working on a rusty old car my two cents is this is now in my "must have' category.

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.

Soft metal motorcycle drain plug was seized and head rounded out. First tried attaching this nut extractor with a socket wrench did not bite well. Then tried an impact gun and it worked easily. No damage to the extractor socket. Saved me a lot of additional cost taking the bike to the shop.

good
