    Hi
    I’m about to lay some Plywood 6mm over a chipboard floor 18mm to even it out.

    What type and size of screws should I use for the above?
    How far apart should the screws be screwed?

    Thank you in advanced

    20mm will do the job and won't go through the bottom of the chipboard into any pipes etc.

    Around 200mm centers for spacing.

    Go upto a 4.0x20 in either of those types the heads on the 3.0mm ones are a bit small and may pull through.

    Is pre-drilling or countersinking needed for the 4.0x20?

    I had no need when fixing my floor, but I used 9mm ply . Straight in....No probs. :D

    They may self countersink or not, try it and see.

    Self countersinking working as long as angle is true. Keeping with small heads even with risk of pulling through. Thanks for advice
