CTA Tools 9030 Fluted Screw Extractor Set, 5-Piece

Needed these for the husband and worked as should.

These. saved. my. a**. Don't ask me how but one of my spark plugs snapped off; you know that feeling of dread when something happens during a project and you're like "oh no, that's going to be expensive". Yeah it was that moment. Like others have said, take your time. Hammer it in, double check you don't puncture the cylinder head. Take your time, slow consistent torque is the key.

I have had better results with the straight fluted extractors like these then the spiral fluted designs. I just wish they cam with the next size bigger and were not square. It if were a 6 flute design then you could use a normal socket on them to get more leverage.

It removed the screw. Will see how long they last.

The quality of this product could be better. They have worked well for the most part, but they do twist over time

I have a 2004 Dodge Durango 5.7 Hemi and that I purchased with 197,000 miles. I always change plugs on a used vehicle when I first buy one. NEVER had a problem till this time. ALL plugs were extremely tight, hard to turn loose. The 4th plug hole from the front, on the right side broke off, these plugs sit DEEP in the cylinder head. I WAS DEVASTATED, and stressed out to the max. Figured I was screwed big time, faced with towing it somewhere or attempting to pull the heads myself. Anyway, it took about 3 days getting the broke plug out, and my friends help, and soaking in PB Blaster. YOU HAVE TO PUNCH OUT THE CENTER OF THE BROKEN PLUG, and then drive the extractor in the center of the remaining threaded metal part of the plug. TURN COUNTER CLOCKWISE, I used the 2nd to biggest extractor. I can’t put all instructions and details on here, it would take too long. When you punch/knock out the remaining porcelain, the end WILL FALL INTO THE CYLINDER HEAD but you can get it out, it won’t fall down far into No Mans Land And Disappear. We made some punch tools and a magnet on a wire. The big body style durango hemi’s are not fun to change plugs.

I bought these because I read some guys online saying they are worth buying for stuck bolts. I was redoing my knock sensors today and the front one was spinning inside itself. I drilled holes in the sensor and it would still not come out. Smacked it with a hammer a few times and it broke lose except it kept spinning. I then pulled on it with needle nose pliers and it snapped off flush with the post. I had a small panic attack. The sensor I was replacing is quite vital and I spent 4 hours trying to get that damn thing out. Then I remembered I bought these fluted extractors. So I drilled a big hole down the post being sure to avoid the threads. Then I took out of these bits and smacked it down into the hole with a 5lbs mallet. Took my adjustable wrench and I applied a good amount of leverage and managed to back the mother effer out of the hole!!! These are probably one of the best tool investments I have ever made.
