The product looks good and I believe it will do what they promise. Unfortunately, the problem is the size. I had a 3/4" bolt hole that needed cleaning, so I ordered this hole a size 11/16 through 13/16. You should be referring to the physical size of the hole, not the size of the screw. Great for my needs. So I ordered the next two sizes smaller and hope one of them fits. Whichever option worked, I'll leave feedback on it and send another one back. When ordering these items, be sure to order the item that matches the physical dimensions of the bolt hole and not necessarily the size that matches the SAE bolt size.
