Original FLOORBOARD SCREWS - FR-111A

screw heads screw tip Pozidriv screws

For MGA, original floorboard screws are BMC# CPZ0416
Countersunk Pointed Zinc 1/4-28-UNF x 1
They are Phillips slotted screws, (Pozidriv screws were not introduced until after MGA was out of production).
The pointed tip can be a concours issue, even though a socket head or Phillips slotted head and flat washer may be hidden under carpet.

screw heads The washer is BMC part number 64401 Countersunk Cup Washer (zinc plated). This is similar to a finishing washer, except it has a wide flange around the outer edge to distribute the load over a wide area on the soft wood.

I used hex socket flat head screws with flat tips, just because that's what was conveniently available when I needed them, back in the late 70's when parts were harder to find. In place of the flat flange cup washers I used standard flat washers (3/8 size I think) and hit them with a countersink tool to make the screw heads lie flush.
