    This.

    I start all of mind by hand until I can't thread them further, then I torque them down with the chuck on the drill turned down (gradually turning it up until I'm satisfied). I had ONE cross thread and fall out a few years ago and that was enough for me. Now I'm intimidated by a $0.03 piece of metal every time.

    I will also use a spot of normal wood glue on the hurricane nut just so the MDF "solidifies" around it, helping prevent stripping.
    Your results may vary.

      I hear ya! I'll see the MDF separate into layers if I'm not careful around a very close driver cutout edge.

      One other tip I have for any threaded insert really.... I'd rather take a tap and chase out the threads to make sure they are cut correctly before inserting them into the cabinet. I'm always paranoid that the dip coating that gets applied to some of these doesn't preserve the thread form correctly, thus causing me to torque the insert out of the hole!

      +1 on the EZ-Lok brand! and #1 on some form of wood glue or epoxy during install to make sure they don't come out under normal uses (not me being an idiot and continuing to torque on a screw that's clearly snagged on something!)

        If your pulling them out,,,,,,your overtightening them! Buy yourself a torque limiting screwdriver. Most guys over tighten screws. It’s in our DNA! If a little is good, more has to be better, right?

        Good luck, Mark
        It's my help that has had the issues and with 50 cabinets of this design it is more likely to find some problems!

        My guess: 15. His grammar is passable. His trolling is good.

          If I am working with MDF and do not have a lot of space; I pre-drill, fill the hole and surrounding area with 5 min epoxy, re-drill to clean out any epoxy, then use deep thread wood screws.
