In an Assa 6000 lock, the top pins are referred to as spool drivers. These pins are designed in a specific way to enhance the security of the lock. Spool drivers feature a narrowed center section that creates a false set when they are improperly aligned during the picking process. This characteristic makes them effective in deterring lock picking, as they can be more challenging to set properly compared to standard driver pins. The presence of spool drivers adds an additional layer of complexity to the lock mechanism, making it more resistant to unauthorized entry.

Driver pins in general do not have this specific shape and functionality, while spring pins and warded pins serve different purposes in locking mechanisms. Spring pins, for instance, are typically part of the action mechanism that allows the pins to reset after being manipulated. Warded pins are used in older, simpler lock designs and are not found in modern, high-security locks like the Assa 6000. Understanding the role of spool drivers within the context of lock design is crucial for anyone preparing for the locksmith test.
