Installing 1/4" plywood

[desgnr]

I am patching an area of kitchen floor where a cabinet was removed. The vinyl floor has 1/4" plywood underlayment. To add 1/4" plywood to the area what size & type screw should i use ?

[RicodJour]

I use underlayment nails.

As RicodJour said, underlayment nails (ring shank) are good. Try and pull one out that's been driven in correctly. If you do use screws,

1-1/4 should give you penetration just through the subfloor (3/4 subfloor + 1/4 plywood + 1/4 penetration).

I often use Phillips "Green" screws.

- Won't rust / Won't strip / Won't snap

For these, Phillips makes a bit (used to be included in 5lb boxes) that locks in them very nicely for torquing to countersink.

Good way to do it. If you need more security also use a construction adhesive, particularly at the edges.
