Amartisan Impact Bolt Extractor Tool, 13PC Bolt Nut Removal Extractor Socket Tool Set

These extractors were positively reviewed on "Project Farm". I decided to give them a chance. These are the only socket extractors I have tried. I live in Michigan, prime salt and rust country. I have a 2008 Dodge Ram 1500 with a 4.7L engine. Both exhaust manifolds were leaking. Each manifold is attached with 4 M8X1.25 studs (13mm head), and 5 M8X1.25 bolts (10mm head). This translates to 18 bolts I need to remove (plus the four nuts holding the exhaust shield to the passenger manifold). The bolts and studs have thread locker on them. I was able to remove all of the 13mm studs without standard tools (8 of 18 problems solved). The stupid 10mm bolts were another story. [MOPAR: PUT A DECENT HEAD ON THESE BOLTS YOU LOUSY @#$@#$^#@$!%@]. Two of the 10mm bolts were broken; the reason for the exhaust leakage. Of the remaining 8 10mm bolts, I was able to remove three with standard tools (11 of 18 problems solved, 2 remaining severe problems). This left me with 5 bolts, four of which had severely damaged heads. With this tool set I was able to remove three of the four damaged bolts quite easily. I tapped the sockets on to the bolt heads, tapped the wrench with a brass hammer, and frequently smacked the extractor sockets back on the bolts heads This worked great. In minutes the bolts came free. The socket extractors gripped the damaged bolts famously (14 problems solved, 2 severe problems). The extractors gripped the fourth bolt as easily as the first three, and SNAPPED the bolt head (14 problems solved, 3 severe problems). The last bolt is the only issue I have with this set. The last bolt head is too small for the 3/8" to grab, but too big for the 8mm. Try as I may, I can't drive the 8mm into the head of the last bolt. The 3/8" spins freely. If this set had a 9mm, I think these extractors would make easy work of it. I drove all of the extractors onto the bolt heads with brass hammers and a large steel drift. I beat the crap out of them. After all the pounding and torque, the sockets look great! I really like this set. I wish they had a 9mm socket, so I didn't have to break out the welder. I guess the welder is coming out for some of the broken bolts anyway, so it's no a big deal. I highly recommend this set. You will not be sorry (unless you need a 9mm)!

Works as advertised, and wonderfully I might add. In my case, I had a lug nut on a kids quad that I smoked with a large impact gun. Hammered the 14mm on and was able to easily remove and replace the damaged nut. Will be keeping this kit handy for future issues.

Material it is very durable. Comes in its own storage container.

Great tool

Old stubborn /broken bolts come out easily

Works great!

Have had a couple of times where customers bring in cars with already stripped bolt heads. This tool does a really great job at gripping, the tapered end is fantastic, these sockets can be used more than one time as long as you use them correctly. Other extractors are usually a one time use whereas this one has proven to me that it can be used multiple times. Super great tool

I ordered this set because my 20 year old Craftsman set didn't have the size I needed. This set doesn't have nearly the bite my Craftsman set does. It will probably work on a broken bolt that isn't really stuck, but I have been able to remove a single broken bolt with it yet and I have tried 3. 2 of them I was able to get out with my craftsman set. The 3rd I had to find another solution for.
