Trouble screwing down 1/2" plywood underlayment
Paul

In preparation for the installation of LVP flooring, I am raising the floor 1/2" to match that of an adjoining room's tile floor.  The plan was to lay down 1/2" plywood over the existing 3/4" plywood subfloor and fasten with #8 1-1/4" wood screws.  The issue I'm running into is that many of the screws strip out before the head countersinks flush with the surface.  I have tried a couple brands without a ton of success.    Any suggestions on how to overcome this problem would be greatly appreciated.

 

Thanks,
Paul

Are you predrilling the holes? Do the screws have a cutter on the tip? Do the screws have threads all the way up to the head? You are not giving enough information about the type of screw. Measure up from the tip 1/4 of an inch. See how many threads are leaft from that point to the head. Sounds like you are running out of threads to hold anything. I do hope that you are not choosing just any screw for this task.
