Whilst the car is at the painter’s, I’m going through fasteners to clean, blast and plate those that I want in passivated black. I have a question regarding the bonnet latching pin nuts.
The bonnet latching pin is the long pin that comes down from the underside of the bonnet and engages with the latch on the body crossmember. It has a pointed tip, which is slotted for a screwdriver for adjustment. It is retained to the underside of the bonnet assembly by two 7/16" UNF locknuts - see Viart p.350. The book shows these to be plain nuts with a spring washer inbetween.
I’m sorting through the carefully stored fasteners, and the top one of these nuts, although loose in the bag, has marks on it that spell failed spotwelds to me. Should this nut actually be spotwelded to the topside of the assembly (the other way up from in the photo), so the pin just screws into it to set adjustment, and is then held in place by the lower locknut? Has mine come ‘unwelded’, or is this just an odd-looking nut?
Photo attached - I can’t examine the panel it might or might not have been welded to as it’s away at the paintshop.
edit - yes, I know this nut should be body colour.
