Neiko04204A Hex-Head Multispline Screw and Bolt Extractor Set, Easy-Out Screw Extraction, Broken Bolt Remover, Stripped Fastener Tool, 1/8 Inch to 7/8 Inch in 1/32-Inch Increments, CrMo, 25 Pieces

Muy buena calidad y despeño, preferí este a un Bosch y no me decepciono en absoluto

Willing to give these an excellent review based on a very limited amount of use. Had a stubborn allen key screw that I couldn't get removed via traditional methods. It was stainless and very hard to drill, and the deeper extractor set I had (irwin) couldn't bite in. This set worked and after looking closely at the bit I could see zero damage. For reference it was only a m6 screw so not too much force was needed, but this did the job well.

Somehow, somewhere you going to come across a hex bolt or spline bolt that becomes mysteriously tight that it rounds or breaks the tool. This set of bolt extractors made getting this VW Amarok transmission fill bolt out as easy as putting a new one in, well nearly, a bit of force needed. Slowly screw bolt extractor counter clockwise and it will go in to the point of where the hex/spline bolt gives and starts screwing out, easy.Don't use a dremel or cold chisel, these could destroy transmission housing.

So pleased - a month trying to get this stripped bolt off and I was running low on transmission fluid! I don’t write many reviews but hoping this helps the next person.Ok so I had a very badly stripped differential fill Allen plug. Standard plug on a Land Rober SUV. This was semi stripped by prior mechanic and I just made it worse without the right tools. Tried the cold chisel method (you can see from photos I whacked the s&@t out of it and no luck. Bought the other stripped allen key versions on Amazon (the ones that have a slight twist in a standard looking hex/Allen to provide grip) and they just won’t get enough grip (not even close in my case so a big waste of time) if you were as badly stripped out as I was. No chance at all. I was really thinking I would need to learn to weld and go buy a welder to attach another bolt on which was going to be my last resort…Tried this and worked extremely well (was done in 20 minutes) with the following comments:As you can see from the photo I used the 11/32 size which fit about a third of the way into the stripped hex differential plug loose. I tap tapped it in gently with a 3 lb hammer to get it about 2/3 of the way in. You don’t need to be poinding it in hard since these have a slight taper which makes them slightly larger as they go further in. As you can see after massively torquing it at the end while successfully remove the fill plug it was ultimately seated about. 90% down. With the large 15mm sized head you know have a solid place to add a socket with a breaker or heavy duty impact.Other comments - IMO very little chance of this snapping off as I see others concerned about - I can’t attest to the quality of the metal but the size I was able to use makes it less likely it would snap. If I were to use the smallest 5-6 (9/32 or less) of the extractors provided I would be more concerned about putting a long breaker bar but at this size no issues. I ended up having to put a 15mm socket on a two foot breaker bar / pipe to get this to finally come loose. And once it did it was literally just finger screwing the rest of it off. Amazing how a seized bolt will hold until it doesn’t. I tried my 3/8 inch (air) impact gun before the breaker bar which is a low clearance since I didn’t have a ton of space. It’s like 350 foot pounds of torque so a mid range impact and it didn’t budge this differential plug although it MAY have weakened it up a bit so my breaker bar worked easier.Best of luck of luck to those reading this but this is the best of 3-4 methods I used and wish I started here since it was easy.Last bit of advice don’t underestimate how much torque you need to get one of these seized plugs off! And if you are in a tight area and able to use one of the provided extractors with some reasonable girth a long breaker bar is the way to go…
