How to Replace Door Knob Mounting Screws

What You'll Need
Electric screwdriver
Screws (longer than previous ones)

If your door knob begins to jiggle when you grab it, the screws holding the mounting might have become loose. The pressure of being turned, and the force applied via hands to grip the door knob might have loosened the screws or have dug cavities into the wood surrounding the screw so that there is not enough wood to hold the screw in place. Tightening the screw is a simple process that requires a brief trip to your local hardware store for more screws. Follow these steps for a firm, non-jiggling door knob.

Step 1 – Assess the Situation

Try taking your screwdriver and re-tightening the screws in place. If you have an electric screwdriver, use it to tighten the screws as much as they would go. The electric screwdriver will let you know it has reached its maximum when it stops going around. Most door knob mounts only have two screws to hold it in place. Tighten all screws and replace any screws that might have fallen out with time. Now, use force and grip the handle. Pull, tug and turn. See if the screws loosen again after your grip. If this happens, it might be because the wood around your screws has pulled away from the screws and doesn’t provide enough friction for a firm fit.

Step 2 – Trip to the Local Hardware Store

Some screws come with supports for walls that are not strong enough to support the weight of a object hung on it using screws. Buy these supports that matches the size of your existing screw. Don’t forget to take along some screws from your door knob just in case.

Step 3 – Take Apart the Door Knob

Using your screwdriver, manual or electric, take out the screws from the mounting plate. The door knob and its mounting should fall off easily from the door, exposing holes where the screws had gone in.

Step 4 – Hammer in the Supports

Hammer in the supports into each of these holes. The support should not protrude out of the wood.

Step 5 – Re-construct Door Knob

Place the old door knob and its parts over the hole where the support had been hammered in, matching hole for hole. Use the screwdriver to put in the screws into each supports. Tighten as far as they would go.

Of course, if your door knob has lost its luster, become faded and worn, you might think about replacing it. They don’t cost much and a newer door knob might be just the thing to brighten up your old, familiar door.
