16PCS 3/8" Drive Deep Bolt Extractor Set, Impact Bolt Nut Remover Set, Stripped Lug Nut Extraction Socket Set For Narrow Space Removing Broken, Damaged, Frozen, Rusted, Rounded-Off Bolts, Nuts, Stud

One of the nuts stripped on my camshaft position sensor which made it impossible to remove it. This tool kit saved my butt! Within 10 seconds the bolt was off and I was on to the next step of replacing and putting everything back together. Worked well, a++++

Worked good on a stripped bolt. Great for the price must have tool set

Outstanding, worked perfectly. Took longer to get than to do the job I needed it for.

I was a bit skeptical about this set at first because it seemed to good a price. A buddy of mine had a striped spark plug deep inside his F-350 Super Duty 6.8L Triton V10 😳 if you are familiar with this engine then you know how bad it can be when you have to get a plug out that’s been in there 20 years. I did have to use my 1/2 inch impact with a step down to use the extractor, thankfully it came with the set! It bit down and yeeted it right out!

Used these sockets on a lug nut that was extremely stripped. Once I put the correct size socket on it and tapped it on with a mallet, it took the nut off in seconds. The kit has helped me out tremendously and I would recommend if you have a pesky lug nut or bolt that is extremely stripper. This kit will take care of you.

Works as promised had a striped lugnut and it took it off with ease best money I ever spent

A yamaha boat motor lower unit has these four bolts that are the second stupidest design I've seen (after old Jeep torx bolts with the star pointing up so rain settles in there and corrodes the 'teeth'). The hex bolt head points towards another surface, so you can't get any sort of powered tool on it, the distance is pretty short, so many sockets won't fit either, *and* it's only a couple of millimeters (on the other axis) from a perpendicular edge, so short-but-wide sockets also won't fit, nor, for that reason, ratcheting wrenches. But that's okay because if you did manage to squeeze a ratcheting wrench on there and apply force, it'll break the ratchet mechanism anyway before it turns the bolt, because the bolt is so badly seized, obviously. And if you put a normal wrench on there and apply torque, it'll just crush-strip the bolt head, and then slip off and smack you in the shin or go through a window or something, probably. And as mention my socket-ratchet was no good because the sockets were too long for the space in the vertical direction again. (And the ratchet mechanism probably would have broke if it would fit.) Enter these easy-off heads. I had mistakenly planned to put one on an impact driver, forgetting the "there isn't space for that" problem. I briefly tried putting it on a socket-ratchet, but I didn't exert much force since I'd already broken one ratchet on here. I did at least confirm with that that it fits in the space, and grips the bolt well. Finally, I went out and got a breaker bar, put that one of these sockets on it, and bam, suddenly the whole process was easy. An *easy* quarter turn on the breaker bar, switch to the ratcheting socket, a few easy cranks on there, and the bolt was finger-loose! For all four annoying bolts. It was *close* though, the breaker-bar-plus-socket was only just able to fit in the space - it's lucky these sockets are very short. So that's a thing to consider, depending on your use-case - if you're trying to undo a bolt that's down a long hole, these things might be *too* short for you, or at least require some kind of extension piece. For taking the stupid bolts off a yamaha boat motor though - perfect.
