Topec 25Pcs Screw Extractor Set, Hex Head Multi-Spline Easy Out Bolt Extractor Set, Premium High Carbon Steel Rounded Bolt Remover

Great product, work as inspected.

These extractors are extremely useful. Small increments in sizing ensures you will find the perfect size for the job. I did twist one off with a 3/8" drive socket. I learned that these seem to be case hardened, meaning soft inside, but the working surface is very hard. They bite really well, and I believe the working surface will hold up well, even under frequent use. Just be advised that they aren't indestructible, you can overpower them if pushed too far. I had an unusually tight (frozen from galvanic corrosion) set screw. Under most conditions, these will be very effective and extremely useful.

I seldom write 1 star reviews. Matter of fact I can’t remember the last time I did so.Just hoping this review will help others.I bought this kit because I needed to extract a bolt that snapped off in a steering knuckle. Drilled it out as big as possible without compromising the walls. These extractors punched in very easily. Just a couple quick light taps with the handle of a screwdriver and it was secure. I started to crank it counter clockwise and it bit into the bolt very nicely. I was impressed up to this point.I then used a rachet and started the precedure and felt in my hand a slight twist and bam, extractor broke off.This was just done with a rachet, by hand. I wonder if an impact wrench would have been better? Maybe not. I can understand if I was using an extension bar, but wasn’t.As you all know, once an extractor is broken off in a bolt, the problem just got 10 times worse. I ended up just buying a new steering rack and swapping that.So now I’m stuck with an extractor set with one broken size. I suppose the others will be put to use when the time comes, but I’d be hesitant to even use these.So just a heads up, if the bolt you’re working on isn’t seized (mine was yes, but I had PB Blaster soaked it overnight and also used torch and candle wax on it), then maybe these will work. But if it’s seized, spend the extra money on a more trust worthy product. It’ll save you extra headache. Good luck!

Nice economical set for DIYers. Liked that the drill sizes were stamped on the body of easy-out. Worked great for getting a frozen fill plug on a transfer case of my 4x4 Silverado. Couldn't get it with the 3/8 hex socket. My 450ftlb rattle gun stripped it, so it was worth the $39 for me to get it out.

This is an outstanding product. I had a differential fill bolt on a Subaru that was apparently tightened by cocaine fueled gorillas at the factory. Even with a stripped bolt head, using a breaker bar and a little effort, the bolt came out with no slippage of the tool. No marks or deformation were left on the tool itself.
