Bolt stump

In locksmithing, a bolt stump is a rectangular part of a lock located above the talon, and passes through the slot in the levers as the bolt moves. This part is welded or riveted onto the lathe in some earlier locks. Modern lock manufacture allows this to be machined in. Most are directly cast into the blank and then milled smooth for final use.[1]
