The usefulness of a dead bolt must be understood by now, what with its use in most thriller movies. It is the locked deadbolt in most scenarios which delays the killers entry into the house. In technical terms, a deadbolt is defined as any bolt lock which operates independent of a spring action while maintaining the same reliance on a key or knob. These locks cannot be badgered into giving up and can be opened only by using the designated key or knob.
There are three general types of deadbolts, which are:
- Keyless cylinder deadbolt: As the name suggests, there is no requirement of a key. The operation of such a bolt is via finger print scanning or a password. The bolt can be locked alternatively by a knob or button.
- Double cylinder deadbolt: This type of deadbolt is operated by a key on either side. These are an ideal choice when the lock is on a glass door. The only disadvantage of this lock is that they are not convenient to be used for exit or escape doors.
- Single cylinder deadbolt: The simplest type of deadbolt is the single cylinder ones. They are opened via a key on one side and a thumb piece on the inside. The single cylinder deadbolts are ideal for non-glass doors.
A strong deadbolt must have the following qualities:
- The lock must be made of sturdy steel and be at least an inch thick.
- The tapering of the cylindrical locks must be precise and shouldn’t spin so fast that pliers cannot grip it.
- The screws must not be exposed and should be made of hardened steel.
- These connecting screws must be strong enough to pierce through a solid metal shock and the size must be a minimum of a quarter inch in diameter.
Should you install a deadbolt?
If you are unsure on whether you need a deadbolt installed at home or at work, here are a few advantages of this locking system that might help you make the decision:
- This is the only fool-proof locking system that offers complete protection from forceful entry.
- Other types of locks like the standard ones can be opened by using a sharp object like a knife or crowbar. A simple bobby pin can also be used to pick such locks. This is because of the inherent spring action of the lock operation. With deadbolts, the absence of a spring system makes them resilient to breaking by force.
- Deadbolts can be broken, but the time taken is prolonged. This gives enough reaction time.
Although no lock offers complete protection against unlawful entering, a deadlock prolongs the entry time and adds to the home security system.
