In the context of rim locks
, a deadbolt and a latch bolt are two different types of locking mechanisms that serve distinct purposes. Here's the difference between the two:
A deadbolt is a type of locking bolt that extends or retracts using a key or a thumbturn mechanism.
It provides security because it is typically made of hardened steel and extends deeply into the door frame or strike plate when locked.
Deadbolts are often used as the primary locking mechanism on external doors because they are resistant to forced entry methods like picking and bumping.
Deadbolts can be single-cylinder, where they require a key to unlock from the outside and have a thumbturn on the inside, or double-cylinder, which require a key to operate from both the inside and outside.
A latch bolt, also known as a spring bolt or latch, is a locking bolt that automatically retracts when you turn the doorknob from the inside or use a thumbturn mechanism. It does not require a key to operate from the inside.
Latch bolts are commonly found in interior doors, such as bedroom and bathroom doors, where privacy is needed but high-security is not a primary concern.
Unlike deadbolts, latch bolts do not provide as much security against forced entry, as they can be easily bypassed with simple tools like a credit card or a thin piece of metal.
The key difference between a deadbolt and a latch bolt in the context of rim locks is their security and operation. Deadbolts provide security and require a key or thumbturn to operate from both inside and outside, while latch bolts are designed for interior doors, automatically retract when you turn the knob from the inside, and do not require a key for operation from the inside.
