IRWINScrew Extractor, Straight Flute, 6 Piece Set (53645)

Tools appear to be good quality and perform the job as required but do not come with the storage pouch shown in the item listing. Personally, I prefer the straight flute design to the spiral variety as I have had several of the latter type snap on me and they cannot be used for reverse threads. I have only needed to use these a few times, however, so I cannot confirm durability problems encountered by other reviewers.

Like the sizes and being able to use left and right hand threads.

Was recommended by a close friend, working on my motorcycle and one of the chain adjuster bolts broke off, drilled it, heated it and tried taking it off.The extractor broke quite easily..... so all in all, not sure what to say next but yea...!!

First let me say these Extractors size 5 specifically helped me out of a Jam. It easily saved me over $1000 in a shop to have the heads pulled. This got the threaded part of a spark plug out in less than 15 minutes (not counting the overnight Parts Blaster Soak)I ordered these Straight Flute Extractors for work on a Ford Ranger where the Spark Plug HEX broke off in the Head. I had first tried Spiral Extractors however I couldn't get them to bite and pull. Since the spiral causes expansion of the threads it wasn't helping. So I looked online and found these. Wow they got here quick and the quality seemed fine.The prep work to use these was to soak the spark plug tube with Parts blaster or Penetrating oil overnight. I did that last night and just crossed my fingers that it would work. I found the size 5 fit the inside of the plug very well and slightly tapped it in. I had a 13 MM 16 point socket that fit the end of it very well. I took a half inch ratchet and started to turn and it turned but didn't bite. At this point I started to get a little discouraged that I was going to have to get it towed.On second try I hammered the extractor in there. Not very hard but enough where it straightened out and didn't easily move. I then sprayed parts blaster on it and waited 5 minutes. This time when I tried to turn it with the 1/2 inch ratchet it resisted. I put a little pressure and it gave. I though it slipped again but to my surprise it started to spin the threads out. I can no declare how satisfied I am with this product. QUALITY is an understatement.If you need to get out a spark plug and don't think it will work try this.1. Soak the part for at least 24 hours. BE GENEROUS with with liquid wrench or similar product. It will burn off or evaporate when you are done anyway.2 Let it sit at least overnight and maybe spray it a second time and let sit. PATIENCE IS THE KEY!3.Get a size 5 extractor and hammer it into it. As I said no hard hits just tap it in as Happy Gilmore would say.4. Find a good socket that fits the end of the size 5. For me it was a 13 mm 16 point socket. Turn it and see if it gives. If not try soaking longer and if needed use heat. I personally did not need to use a torch to heat it up.5. Have an iced tea or Beer and feel relievedGood luck and don't question the product it works great!
