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.
  • 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.

  • 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.

Lorsque vous installez une vis, tournez d'abord la vis dans le sens anti-horaire ("à gauche") pour "asseoir" la vis.

Tournez lentement jusqu'à sentir la vis descendre d'un cran, puis arrêtez.

Maintenant c'est bon, vous pouvez serrer la vis en toute sécurité.

Une vis bien installée tournera facilement jusqu'au serrage complet.

Une vis avec un mauvais filetage (abîmé ou non adapté au filetage du trou de vis) est de plus en plus difficile à serrer, parce que le filetage mal aligné coupe au travers du filetage du trou de vis, ce qui cause des dommages permanents.

Si votre vis ne se serre pas facilement, faites marche arrière, repositionnez la vis et réessayez.
