In hurricane locks, the lock bolt is especially prone to damage.
When the bolt becomes worn or broken, it is no longer long enough to properly engage the main lock or strike. In many cases, the internal mechanism where the mounting screw secures the bolt also becomes damaged. When this happens, repair is no longer reliable and the entire lock assembly must be replaced.
Slightly simpler version (for customers)
Hurricane locks often fail at the lock bolt. When the bolt breaks or wears down, it cannot fully catch the lock, and the internal screw mount may also be damaged. In these cases, replacement is required rather than repair.
