Latch bolt
The Code of practice: Hardware for fire and escape doors, Issue 5, published by DHF and GAI in November 2024, defines a latch bolt as the 'moving part of a latch that engages the locking plate'.
Latch bolts are a standard part of a lockset or door locking system, the latch is curved on one side and spring-loaded allowing a door to be pushed shut via the curved side of the latch, engaging with the lock plate, springing into a locked position. The latch bolt can be then freed either using the handle (if so designed) or with a key.
