Tips

  • Ensure both screws are tightened evenly before covering the plate.
  • Test the handle functionality after tightening screws.

Common Mistakes to Avoid

1. Over-tightening the set screws

Reason: Applying excessive force can strip the screw threads or damage the doorknob mechanism.
Solution: Tighten the screws firmly but gently, using the correct size screwdriver and avoiding excessive pressure.

2. Ignoring stripped screw holes

Reason: Stripped screw holes prevent the set screws from gripping properly, leading to a loose doorknob.
Solution: Use wood glue and toothpicks or a screw hole repair kit to fill the stripped holes before reinstalling the screws.

3. Using the wrong size or type of screwdriver

Reason: Incorrect screwdrivers can damage the screw heads or not provide enough torque to secure the doorknob.
Solution: Use a screwdriver that precisely fits the screw heads and provides enough grip to tighten the screws without slipping.

FAQs

My doorknob is loose but the screws are already tight. What should I do?
If the screws are tight but the doorknob is still loose, the problem likely lies within the doorknob mechanism itself. The mounting plate inside the door may be loose or damaged. You may need to remove the doorknob completely and inspect the mounting plate for any damage or looseness. You might need to replace the entire doorknob if the plate is broken.
What tools do I need to fix a loose quick-set doorknob?
You'll primarily need a screwdriver (likely a Phillips head), but depending on the situation, you may also want to have a hammer, pliers, and perhaps a small level handy for ensuring proper alignment. In some cases, a replacement screw or even a small amount of wood glue may be useful if the original mounting holes are stripped.
