Maybe it doesn't ruin the screw, but it is definitely very very inconvenient to screw the nuts.
What, now in order to unscrew the nut I have to use two tools instead of one?
I did this about an hour ago and when I wanted to unscrew the nut in order to switch the wheels it simply wasn't possible, the axle spun non-stop even when there were two tools on each nut, in fact, the nut that I wanted to remove, that was screwed right to the end, I wasn't able to. It got to a situation where I removed the whole axle and I found it hard to put back because I put it in incorrectly, and then I removed it with a plier and after I understand that you have to put it in differently, I put it in the right way easily, but the problem is that every slight touch on the axle causes it to move. In one second I can pull out the axle from the hanger, have I ruined the axle?
This has just been a disaster.
