The nomenclature used by each manufacturer to describe the size of the fastener or the hole size it goes into might be confusing when looking at body bolts, sheet metal screws and related U-clips, and even automotive fasteners.
Some manufacturers may list a panel fastener as fitting a 1/4″ hole and others will list it as fitting a 6.35mm hole.
