Does anyone know what the fasteners (screws) used to attach the plywood floor to the aluminum cross members are called? They appear to be 1/4-20 flat head, countersunk, torx drive screws of some sort.

On my 260 there are 1/4" pop rivets holding the plywood flooring to the
stringers.
The cover for the wireway Phillips screws hold the cover on it.

On my '78's they are steel self-drilling flathead torx head screws. I replaced some with phillips heads as they were available locally @ ACE Hardware.
