Mayhew Tools 37332 Screw Extractor Set, 5-Piece, Black Oxide Finish

Strong and versatile to use!

This actually works. Used it to get a broken spark plug out of my riding mower.

Excellent tool. Exceeded my expectations.

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

Removed broken spark plug on gm 3.8 back of motor # 2 cylinder. Very tight space and difficult to get too, but these did the job without breaking easy out..

Great value for the money quality is decent

I had these and the smallest broke on the first use. That’s fine, it happens. The warranty process however was a nightmare. Mathew told me to contact the seller. Amazon was the seller and said it was outside the return date. Back and forth with Mayhew and Amazon. Amazon finally agreed to refund me upon return of item. This took some time. They are much shorter than my snap on set. I will replace these with the proto extractors as I need the small sizes that snap on doesn’t offer.

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.
