THINKWORK Bolt Extractor Kit, 13+1 Pieces Nut Extractor Socket Set, 3/8" Drive Rounded Bolt Remover, Lug Nut Removal Tool for Damaged, Rusted, Rounded-Off, Stripped Fasteners

Like another reviewer said this is a lifesaver, or at least saves a huge amount of time and expense and stress. Oil pan bolt seized and the head rounded, tried lubricating oil and impact driver with no luck, this kit got it right off on the first go. So grateful, thank you, thank you!

I had 3 rusted-on #10 machine screws in my 2007 F-150 alternator mounting bracket. I wasn't having any luck with my socket - stripped them to hell. A few thwacks with a hammer with these little extractor sockets and every one of them was removed with ease. I was pretty shocked. I'll mention, though, that one bolt needed to be removed with an extractor socket that was a size smaller than the screw head because it was so rusted. Still worked great. Would highly recommend.

item is well made, materials are hard enough to loosen bolts without breaking or distorting tool, a must have tool

worked exactly as advertised, I was having trouble getting off a stripped bolt, purchased these and within a matter of minutes had the bolt removed. Well worth the money.

This seems like a good tool for extracting, however, I tried this on a brass fitting and it chewed up the fitting without extraction. Probably not the tool's fault because brass it soft, but the design feature is aggressive enough to shave brass rather than gripping it. May work much better on steel or harder metals.

Had a coolant block drain nut that was rounded off from previous owner on my 2016 tundra 5.7 and when doin the coolant change gave me lots of problems tring to get it out sense there wasn't much room to work. This 10mm extractor got it out first try. I'm very happy with these and wish I would of got them sooner.

If you don't have one, you better get one. This bolt socket extractor kit saved me so much time. One of my engine exhaust manifold bolt had rounded off and I got this tool. I hammer it the socket in and zap it off with a impact and it came right off. Good product I would recommend it to anyone

These things were a lifesaver I had a stripped out oil plug on my Honda odyssey took the 17mm one tapped it on the plug and it cranked it right out. Put the socket in a vice and with a Phillips head screwdriver tapped the stripped out oil plug from the socket
