Yesterday I decided to pick up one of their Doyle rivet nut tools (58078) since I've needed to get one. Bring it home & open it up to find that it was missing the M8 head but had the other five & all six sizes og rivet nuts. Fine, going back to mall for the cruise this evening so I figured it could be swapped out when we got there. Easy swap, went to grab another but decided to check it out at the register. This one was missing the M8 too. Hmm. Go grab the last one left & check it out too for the same result, missing the M8. I'm guessing if they had more they all would be missing it. But I have to give them credit that atleast it had the storage container for it.
