The screw on the door lock is loose. What's the matter?

The screw plays a fastening role, and the vibration caused by frequent opening and closing of the door lock will cause the screw to loosen. WorldCom screw manufacturers suggest using cross screws first to see if they can be tightened. If the screw is not tightened, check whether it is slipping and replace it with a new screw fastener.
