dead bolt
Secure door fastener
A dead bolt is a lock mechanism that extends a solid metal bolt into the door frame, operated by turning a key or thumb turn rather than a spring.
Unlike spring latches, dead bolts can't be pushed back without the key, making them more secure: Make sure you lock the dead bolt when you leave.
Also spelled deadbolt.
