Dead bolt

A dead bolt, deadbolt or dead lock is a locking mechanism distinct from a spring bolt lock because a deadbolt cannot be moved to the open position except by rotating the lock cylinder with the key. The more common spring bolt lock uses a spring to hold the bolt in place, allowing retraction by applying force to the bolt itself. A deadbolt can therefore make a door more resistant to entry without the correct key.

A deadbolt is often used to complement a spring-bolt lock on an entry door to a building.

Common types

A deadlock, if it is cylinder operated, may be either single cylinder or double cylinder. A single cylinder deadlock will accept a key on one side of the lock, but is operated by a twist knob on the other side. Double cylinder locks will accept a key on both sides and therefore do not require (and often do not have) any twist knob. This prevents unwanted unlocking of the door by forced access to the interior twist knob (via a nearby window, for example). Double cylinder locks are sometimes banned from areas because they can be difficult to open from the inside and violate fire safety regulations. Some lock manufacturers also have a "lockable" knob: a key is always needed on one side (usually external), and a twist knob can be used on the other (internal), unless a button has been pressed, in which case a key is also needed on the internal side.

Etymology and definitions

The word was first recorded in 1632, probably as a form of Onomatopoeia. It shares its beginning consonants with several other English words related to violence, such as "slash", "slay", and "slam". The word is found in several English colloquialisms, such as, "slap fight", "slap-happy", "slapshot", "slapstick", "slap on the wrist" (as a mild punishment), "slap in the face" (as an insult or, alternatively, as a reproof against a lewd or insulting comment), and "slap on the back" (an expression of friendship or congratulations). A slap with the back of the hand is typically identified as a "backhand slap" and, on occasion, a "pimp slap." In jazz and other styles of music, the term refers to the action of pulling an instrument's strings back and allowing them to smack the instrument (see Slapping (music)).

"Bitch slap" is African-American slang that dates back to the 1990s. It is used to mean killing a woman, or to refer to a woman hitting a man, or a woman or gay man haranguing somebody, or a man hitting someone else in an effeminate way. Bitch slap has also been used in American prisons since the 1990s to refer to slapping instead of punching, with the implication that the perpetrator isn't "man enough" to deliver a closed-fist punch.
