The appropriate door latch bolt size depends on the thickness of the door where it will be installed. Measure the thickness of your door, then select a bolt that is the same length or slightly longer than the measurement obtained.

A door latch bolt is a spring-loaded bolt that is retracted when the door handle is turned. It is designed to keep the door closed but can be easily opened from either side. A deadbolt, on the other hand, is a more secure type of lock that requires a key to operate. It is typically used on exterior doors.

Door latch bolts are commonly made from durable materials such as stainless steel, brass, and zinc-plated steel to withstand regular use and provide protection against corrosion.

Replacing a worn-out door latch bolt is a relatively simple task. Remove the old bolt by unscrewing it from the door frame, then insert the new bolt and secure it in place with screws. Ensure you choose a bolt compatible with your door's thickness and the strike plate on the door jamb.
