Axial rotation

Axial rotation

Axial rotation is a concept primarily used in pin-tumbler locks that requires locking components be properly raised and rotated in order to unlock the lock. Most axial rotation systems accomplish rotation through a specially cut key and component design which allows the components to rest in a rotated state once the key is fully inserted into the lock.

Since 1968, axial rotation in pin-tumblers has been primarily associated with Medeco brand locks.
