I got these to remove a rounded bolt. It took a few try but it got the job done. I always get craftsman tool because the are the best quality with the best price.
I broke one and found out then that there is no warranty on these. They are also not sold seperately. If I had known that, never would have bought them in the first place.
These may work excellent, but I never got the chance to use them. Ordered online for in store pickup and suspected something was wrong that set was not on the floor. There are different set and the description says works with 3/8 drive. The set they brought out to me was the low profile that has a round hole and only work with a wrench. Told the guy that is the wrong set so he returned them and will look for an extractor set that will work on a 13 mm bolt. Getting frustrated with Sears and Craftsman as they have items on but not in the store.
I wish I had bought this set 10 years ago. I can't tell you how many times I've dealt with rusted / rounded off nuts and bolts. And how much time I've wasted. I already used this kit and like magic, the old nut came right off. No more hacksawing or chiseling to break the old nuts once they round off. This kit was 1-2-3 and off it came. Thank you for making a great economical Craftsman set. Comes in nice compact case too to keep all the pieces together.
Perfect solution for removing my decades-old oil drain plug from the lawn tractor. Took a couple sizes to do the trick along with a dose of persistence, but SUCCESS! Great addition to any tool set.
