There is a nut (and set screw) in each front corner of the hood on my 2014 4/4 with easy-up hood. Although the nuts are self locking, the driver's side one kept coming loose and was eventually lost. An M6 self locking nut "sort of" fits for now. I was originally advised not to over tighten these nuts as it can lead to bracket breakage in the front corner of the hood.
Does anyone know exactly what the thread is on this part of the hood? It looks finer than M6 and I don't haver a thread guage.
Additionally, if I can find a source of T type self locking nuts (thinner), then the nut won't come loose so easily as more of the self locking element will be engaged with the screw's thread. Struggling to find anyone online with a wide variety of T type self locking nuts.
