Wax Coating Screws to Prevent Wood Splitting

Wax Coating Screws To Prevent Wood Splitting

When driving a wood screw into wood without a pilot hole, I like to wax my screws to help prevent splitting. I found it time consuming to sit and rub bee’s wax or candle wax on each screw, so I came up with this idea.

Wax Coating Screws To Prevent Wood SplittingTake a toilet seal wax ring (around $2.00 at any hardware store) and melt it into an empty small dog/cat food can. This way, all you have to do is dip the screw into the wax and pull it out. The threads hold on to the soft wax for a perfect coating.

You can purchase cup warmers or candle warmers at just about any craft store.I use a plastic can lid to keep the wax from getting on anything else when I need to carry it in my toolbox.

    This is a excellent technique. I learned about this idea years ago but forgot about it. Thanks for the reminder.

    when building decks with pressure treated wood and deck screws to secure mitred corners I simply put my impact driver in reverse and with some added pressure produce a pilot hole
    seconds later I throw my drill into forward and sink my screw without any splitting

    How, exactly, does waxing prevent splitting? I use wax because it prevents grabbing and seals.

      Hi Dave. Putting wax, or soap, on a screw is mostly about lubricating the screw so it drives easier. Because it drives easier, it may also help prevent splitting. But if there’s any question it’s still best to predrill.
