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 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, as well as make the door more resistant to forced entry.
A deadbolt is often used to complement a spring-bolt lock on an entry door to a building.

Deadbolt Underscored - 2 months ago by Deadbolt The film industry can be an extremely rewarding and lucrative sector – for both – the investors as well as the creators. With the growth of widely accessible entertainment platforms, such as Netflix or YouTube, audiences today are able to watch practically any film they choose on-demand. Deadbolts are thicker and heavier than spring latches, and they are not rounded or angled at the end. They are normally comprised of steel, bronze or brass, and they extend deeper into the door frame–typically about one inch–than spring latches. The 980 deadbolt is both tough and attractive. The crisp, clean appearance of the satin nickel finish adds to the overall look of the product and brings a modern feel. The single cylinder deadbolt can be locked or unlocked by a key on the outside, or the turn button on the inside.
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.
A variant of the standard deadbolt is the vertical deadbolt, invented by Samuel Segal. Vertical deadbolts resist jimmying, in which an intruder inserts a pry bar between the door and the jamb and attempts to pry the bolt out of the door.
Other types of deadbolts include:
The double cylinder design raises a safety issue. In the event of a fire, occupants will be prevented from escaping through double-cylinder locked doors unless the correct key is used. This is often an avoidable cause of death in house fires. The risk can be mitigated by locking the deadlock only when there are no occupants inside the building, or leaving the key near the keyhole. Some fire departments suggest putting the key on a small nail or screw near the door at floor level, since the cleanest air is at floor level and you may be crawling to get to the exit, thus placing the key where it is easiest to find.
Note that single cylinder dead locks (with an unlocked twist mechanism on the inside of the door) do not have this problem, and therefore are most commonly used on fire exits. Some areas have fire safety codes that do not allow a locked exit.

Deadbolt is an American rock band from San Diego, California, U.S. They describe themselves as 'The Scariest Band in the World.' The band often features two or more bass players, who are called 'The Wall of Thunder.'
The band originally formed in 1988 as a trio, featuring guitarist and vocalist Harley Davidson, bassist and vocalist Robert 'RA' MacLean and drummer Les Vegas. Both Vegas and MacLean have since left the band. Vegas' departure is chronicled in the song 'Po' Boy' on the album Hobo Babylon. The other current members of the band are bassist Gary '3rd Degree' Burns (part of the band's 'Wall Of Thunder') and drummer Tank Johnson. Tank Johnson died on January 11, 2015. Former members of the band include The PhanTom (bass and guitar), Claymore Mines (bass), The Coroner (bass), Coffin Boy (bass), Moose Cutter (bass), and Mark Davidson (Harley's brother) aka Lord Von Crappo who still occasionally plays with the band. Vocalist/guitarist Diana Death occasionally contributes.
Deadbolt's music combines surf rock, goth, psychobilly and blues sound with unusual and offbeat lyrics, a style the band dubbed 'voodoobilly.' Besides the release of several CDs, the band has toured both North America and Europe extensively.
The band is known for its use of power tools during their live sets, and it is customary to be showered with sparks of red-hot metal during their live shows.
Three members of the band were also in a short-lived offshoot group called The Strangers 1800, which performed music from Spaghetti Western films and TV westerns and released one EP, When Men Were Men and the Sheep Were Scaredand one split record with Deadbolt on Goldenrod Records.'
