Mayhew Pro 37331 Screw Extractor Set, 4-Piece

Works perfect! I needed to remove a broken spark plug and I asked around to see if any mechanic in my area was willing to help. No help. So I took matters into my own hands and I was able to remove the spark plug using the 3/4” screw extractor and my car works perfectly fine now. I recommend letting the spark plug sit in PB blaster for at least a day.

Very good extractors. Most extractors don't bite very well of want to twist or break off themselves. I have had very good luck extracting bolts with these. These are my go to bolt extracts if they won't extract it, its straight to drill bit and or die grinder.

Threads broke off inside the head while removing the #1 spark plug. Was expecting it to snap off while using it because of how severely stuck it was and how hard I was pulling on the socket wrench to get the plug out, but it amazingly got the plug out quickly. Just used a torch and “freeze it” aerosol can to help shock the threads, even twisted the easy out slightly when I was done with it which was expected in my situation. Overall couldn’t have asked for a better result in using these, very strong steel, definitely high quality.

Extracted a broken spark plug from a minivan. Saved the day. Good product

My 05 ford explorer with the 4.6l 2v had a spark plug blow in half with the threaded portion stuck in the head and this tool was just strong enough to get it out. We used the biggest 3/8" extractor with an 8" long 3/8" extention attached backwards with tape and an allen key socket to make a female to female 3/8" adapter on the other end to attach a 3/8" breaker bar and as sketchy as it was the extractor got it out. Would recommend just take your time and use lots of penatrating oil.

Leaving 3 stars because I haven't used the larger ones yet, but the 1/8 extractor snapped with ease while trying to remove a small corroded bolt. Working in an industrial environment where water and abrasive materials are present. Would have probably worked great on a clean bolt. Definitely is not a heavy duty kit for extreme environments

When I heard that spark plug pop, and the insulator came out in my hands, I thought for sure I was in for an engine head rebuild. I did some research and found out the square easy out tools, where the best bet for something like this because the spiral tools tend to spread out the spark plug threads inside the hole making it harder to remove. This kit showed up within a day. The quality is exceptional. The storage pouch is high-quality. The edges of the tool were very sharp, so I knew they were going to dig in to the threads easily. Of course, the spark plug that broke off was in the most inconvenient place behind the suspension spring. So I had to use a long combination of extensions and a socket designed for square oil pan bolts. see pic. (This is on a Ford F250 so I removed the inner fender-well to gain access to the plugs, thus needing the extensions) I used gorilla tape to secure the socket and easyout bit to the extensions. I also pre-soaked the spark plug threads with PB blaster a few times a day for a few days to loosen up the corrosion. You really have to hammer the easy out in pretty good to get it to bite, and use a very stiff extension. Once I did that, it came right out. I was thrilled. I couldn’t believe it actually had come out. Hallelujah! The clouds parted and the sun shown through (well the moon since I was up til midnight messing with it) This time I made sure to put some copper anti-seize grease on the spark plug threads to make sure the dissimilar metal corrosion couldn’t occur. The combination of an aluminum head with a steel spark plug caused galvanic corrosion (look it up, it’s real) that locked the spark plug into the head. The copper anti-seize provides a barrier that allows the current to flow between the head and the spark plug threads. Highly recommend.

This worked amazing! Used it to remove a broken spark plug that was rusted to the block I was worried it would break because of the force needed to get it out but no problem.

Parts received were as described and well packaged
