Whenever you install a screw, first turn the screw counter-clockwise (in the “loosey” direction) to “seat” the screw. Turn slowly until you feel the screw level off and sink slightly, then stop. Now it's safe to tighten the screw.

  • Now it's safe to tighten the screw.

  • A properly installed screw will turn easily until it's fully tight.

  • An improperly threaded screw gets increasingly difficult to tighten—because the misaligned threads are cutting across the threads in the screw hole, causing permanent damage. This is known as "cross-threading."

  • If your screw doesn't tighten easily, back off and carefully re-seat it, and try again.
