GEARWRENCH 15 Pc. 1/4" & 3/8" Drive Bolt Biter™ Impact Extraction Socket Set - 84783

I bought the Gearwrench bolt extractor set on a whim after struggling with a rounded-off bolt on my truck’s exhaust manifold. Honestly, I wasn’t expecting miracles, but this thing worked like a charm. The fit was snug, the grip was tight, and with a little muscle (and a cordless impact), that stubborn bolt came right out.What impressed me most was the build quality—these extractors feel solid and well-machined. They didn’t strip or deform even under serious torque.If you’re like me and always end up dealing with frozen or mangled bolts, this kit is a must-have. Worth every penny!

Had a stripped oil drain plug Bolt (spent three hours trying to get it out without the Bolt Biter), but once the set was delivered, a few attempts later, I got the Bolt to move and it's the best feeling in the world!!! These Sockets are a MUST HAVE for every D.I.Y.'er. A totally AMAZING TOOL!!!

The media could not be loaded. Was able to remove rounded torque converter bolt.

These sockets are worth their weight when you need to remove a rounded or heavily rusted piece of hardware. Tap it in place with a hammer and use a ratchet or impact gun to easily remove that stuck fastener.

Very well built. Work very well highly recommended

They work great. Very easy to use. Build quality is good Very strong. Happy with the price

I don't write many reviews let alone positive ones so that should tell you something right there. As for this product the straight flute design is a great idea and is why I chose this product over the typical spiral/conical/one directional flutes that everyone else makes. 1. As mentioned in the description, straight flutes allow you to loosen and tighten. This is incredibly helpful when gently working a fastener free so as not to break off the stud or bolt in the part. 2. Other designs that "cut" into the fastener can ruin threaded studs that go past the nut, especially when severely corroded and you have to use the smallest extractor possible.That being said, I have recently removed exhaust flange nuts that were practically disintegrated down to the threads on the studs. Access was also limited as the flange had a deep lip that went around the perimeter preventing the use of vice grips or a splitter, it had to be a socket. These were 14mm nuts some of which were so bad I had to use the 11mm bolt biter to spin them off. I thought this would definitely gall the studs a little, but there was just enough bite to grab the smallest amount of metal and spin the nut. Remember, these don't cut/dig into the fastener like other designs which would have ruined my studs. After that all I had to do was run a die over the studs to clean up the roots of the threads and they were good to go.Looking at my pics you would think that can't be real....yeah, and so did I when I was taking apart my exhaust. And, yes, you can actually see between the individual threads of some of those nuts they were that far gone. To be fair, I did employ the usual old school tactics pre soaking with penetrating fluid and using a torch to "break" the corrosion that fuses everything together. Anything less would have made this task impossible regardless of how great the tool. You have to put in your due diligence to solve your particular problem/situation. Don't expect any tool to save your ass, use your head and figure it out. The tool is merely an aid to your success and this particular design allowed me to do just that.I knocked off one star because these are made in China. I should actually give it only two stars because it's made in China maybe even no stars, but I think the design is fantastic and I want to give credit where it's due. I would have gladly paid more for these if made in the USA.

Must have in a shop that does oil changes all day and comes across those stripped off drain plugs. Has been a life saver!
