After stripping back an old step ladder it now needs to be reassembled. During the disassembly the bolts allowing the ladder to fold had to be cut off due to the one shot nature of their design. The inwards facing bolt ends were basically riveted over?
I've got some threaded bolts which fit nicely (see photos) but the question is, what nut should I use to secure the other end? Obviously, just one bolt will work itself loose fairly quickly after opening and closing the ladder a few times. I could use 2 bolts to lessen the chances or use a lock nut perhaps? But they're not really used for this purpose, i.e. securing a bolt which is supposed to allow constant rotation.
Does anyone know if there's a specific bolt or method I should be using in these cases? Preferably something which isn't one shot either. Allowing the ladder to be disassembled if needed.
Any advice greatly appreciated.
