Losing nuts

The nut on the cage bolt vibrating loose caused your lockup?

 

If u have to drive around with caged chambers u might wanna get it fixed ?? not sure what else u would mean

 

Tilting at windmills?

 

One of the first things I did when I bought or was assigned a company trailer is to remove the caging bolts from their holders and put them in my tool box. They lay in the bottom of the little red tool box along with the hammers and wrench roll.
I found that winter salt spray will seize them in the holders after one season and after a second season you MAY be able to remove the nut but the chances of moving the bolt are very small, even with a 3lb hammer.
