Dial: The external, numbered dial that you turn to input the combination.
Spindle: The rod connected to the dial that extends into the lock mechanism.
Wheels (or Cams/Discs): A stack of circular discs, typically three or four, mounted on the spindle. Each wheel has a notch or "gate" cut into its edge.
Drive Pin/Fly: A small tab or pin on each wheel that engages with the next wheel in the stack, allowing them to be "picked up" and rotated.
Fence (or Lever): A metal bar that rests above the wheels. When the gates on all the wheels align, the fence can drop into the aligned notches.
Locking Bolt/Shackle: The mechanism that secures the lock (e.g., the part that goes through a hasp on a padlock or the bolt that secures a safe door).
