Mini WSM question

[salahaddin]

I just finished a build with an IMUSA pot. I forgot to buy washers for the bolts holding the grate inside the pot, have any of you had issues with the screws coming loose after several uses? It's all painted so I want to avoid removing the bolts.

I used two nuts and locked one onto the other.  I didn't use washers.  So far ...no loose nuts (besides the cook).
