Acme Locks is the Right choice for Your security plan for home or Industry.

Acme Locks provides :

a. Door Lock with a Deadbolt Type Bolt

b. Every door lock with a bolt that extends from the lock into the strike, which is mounted into or on the doorframe.

c. latch bolts and deadbolts. Some locks combine the two bolts into one.
The latch bolt is a spring-loaded, bevel-shaped bolt. The spring keeps the latch bolt extended. It will retract by turning the door knob or lever handle. When the door is fully closed, the spring-loaded bolt extends into the strike plate about 1/4" to 1/2."
 Latch Bolt
There is also a type of latch bolt called a deadlocking latch bolt which is more difficult to retract when the door is fully closed. The deadlocking latch bolt uses an integral plunger on the face of the bolt that is retracted when the door is closed.

d. Deadlocking Latch Bolt
A deadbolt, on the other hand, is not spring-loaded nor beveled and must be manually retracted and extended. A deadbolt extends farther into the strike plate than a latch bolt: 3/4" to 1". The deadbolt is rectangular in shape and is larger in section and length than a latch bolt. The deadbolt is manually operated by either a thumb-turn or by key.

e. Deadbolt

f. Bored Latch Set

g. Mortise Locks :
Door locks and latches that fall under the Bored and Pre-assembled Locks and Latches category do not have deadbolts. The door locks covered by the other three standards all have or have an option of having deadbolt type bolts and are all subjected to the Bolt Impact Test. The key here is to get a Grade 1 door lock that has a deadbolt type bolt.

Other Door Lock Features
Security Strike Plate -- A strike plate comes with every door lock. Many times these strike plates are cosmetic and not intended to provide much security. They come with two, short 3/4" or 1" screws to attach it to the doorframe and are made of thin gauge metal.

h. Standard Strike Plate and Screws

High security strike plates are available. They sometimes come with a heavy gauge metal reinforcing plate that mounts under the cosmetic strike plate and come with 3" long screws that secure the strike to the wall framing, not just to the doorframe jamb.

The screw holes are staggered so the screws don't penetrate into the same grain of wood in a wood doorframe or wood wall framing member. The concept of screwing into different wood grains in the doorframe and wall framing is to make it more difficult to split the wooddoorframe or wall framing when the door is impacted. This feature should be considered at every exterior door and at those doors coming from attached garages.
