Deadbolt Parts

The thumb-latch (or thumbturn) is the part of your deadbolt inside your home that you use to lock and unlock your deadbolt. 



The deadbolt is the piece of the lock that secures your door shut. 




The turnpiece (also known as a tailpiece) is the portion of your lock that extends through your door from the outer key cylinder to the inside of your door. The thumb latch connects to turn piece in order to operate your lock. Your August lock will attach to this in place of the thumb latch.



The keyhole is where your keys operate your deadbolt.
