Why do my door knobs keep coming loose?
The problem is that the set screw loosened up and is not applying enough pressure against the threaded spindle. This happens as doorknobs age from use. Screws loosen, and doorknobs go wonky. Newer style doorknobs may not have set screws but can still loosen.
How do you fix a door knob that won’t unlatch?
Pull the handle and rosette off of one side of the door to expose the barrel and spring mechanism. Spray the mechanism with spray lubricant while you operate the barrel with the other handle. The spring should loosen enough to allow the barrel to retract. Reassemble the knob when you’re satisfied with its operation.
What is a set screw on a doorknob?
These slotted 1/4-20 set screws are used with vintage style door knobs mounted on threaded spindles. The screw threads through the knob shank and tightens directly onto the spindle (not to be confused with headed set screws used for tightening knobs onto tapped spindles). Made of brass-plated steel.
How do you open a door that has a loose knob?
Use the screwdriver to push the opposite side of the doorknob from the door and latch. Pull the spindle from the center of the latch if applicable. Thread the screwdriver through the large spindle hole in the latch. Pull the screwdriver away from the jamb to retract the latch and release it from the latch strike.
How do you fix a door latch gap?
Strike Adjustments If the gap along the side of your door is so large that the latch won’t catch or barely catches, adjusting the strike can reduce the gap to ensure proper operation. Unscrew the strike and slide cardboard shims behind it, then screw it back in place so the screws pass through the cardboard.
What kind of screws go in door knobs?
Unscrew Your Door Knob Using a Philips-head screwdriver, turn counterclockwise to unscrew a knob with standard hex-head screws. If your knob has a pinhole or small slot opening, use a flathead screwdriver to push it inward. A paperclip or small pin can also be used if the screwdriver is too big.
Where is set screw on door knob?
1. Remove the Knob or Handle. If exposed screws are being used, you will have to find the set screw, which is normally found on the inside of the door. Using either a screwdriver or Allen key, loosen the set screw and remove the handle, which will uncover the shaft.
Should door knobs turn both ways?
The upper part of a knob should turn away from the door latch/lock so one will be clockwise, the other anti. Having them all turn one way is not usual.
What is a dummy half knob?
A half dummy door knob is essentially the same thing as a full dummy door knob but in this case, a single knob or lever is provided. This is perfect for a closet where you only need one doorknob rather than two. Like a full dummy food knob, you only need this for decoration and do not have any other functions.
How do you fill the gap on a door knob?
You can fill that void between the strike plate and door stop with Durhams Rock Hard Putty. It’s a powder that you mix with water. Fill that area so the putty is higher than the jamb surface and you will be able to sand it down to smooth when dry. A bit of primer over the putty and you’ll be ready for paint.

What tool do you use to tighten a set screw?
To tighten new, standard, alloy, cup point set screws, install an allen wrench with the short end in the socket, long end in your hand, and tighten until the wrench bends or twists about 30° (1 hour on a clock face). Then the set screw is as tight as it should be.

Are all door knob screws the same size?
Typically the screws that are with the knobs are long enough to accommodate thicker doors. As long as your door is only 1 3/8″ it can be 1/2″ shorter. Do not get them too long or the screw will bottom out before the handle is drawn tight. My guess is a 10/24 round head screw 1 1/4″ long.

Most pre-hung doors use 1-inch screws for hinges and strike plates. Replacing those short screws with longer screws is the easiest way to improve a door’s ability to withstand a burglar’s kick. These screws have good threads and screw head.
