Mk1V Floorboard Washers

Hello

I am assuming the below washers are for fastening the floorboards on a Mk1V, if so is there a cutout on the edge of the F/B to take the bent edge of the washer or does the washer just sit on the edge with no cutout? What type of head does the fastening have?

Regards Peter

I don’t know about Mark IV, but those same clips are used on XK120 boot floors, and the bent edge just digs into the flat plywood near the edge, and there is a rectangular cutout at the edge where the screw passes through to a captured nut below, and the screw head is round with a screwdriver slot.
