N800576-S426
These are Ford's N800576-S426, which are used to hold the front of the front fender's inner liner to the radiator support. They are M6-1 x 28mm with a 1 1/2" washer. I've not been able to find a source for them so blasted these clean, gave them a phosphate bath, and then powder coated them satin black. In fact, Ford's Standard And Utility Parts Catalog says the N800576-426 is actually only 10mm long, so that part # may not be correct. (DSCN7448)
