EMPLOYMENT: Nose fuze used in German 13-mm ammunition. (See fig. 556.)

Over-all length: 0.594 inch.

Maximum diameter: 0.406 inch.

Threaded length: 0.156 inch.

Number of threads: 5 RH

CONSTRUCTION: The fuze is of single piece construction with a closing cap in the nose and threads on the base for engaging the projectile. A long striker is housed in a central cavity and it is held in place by a centrifugal bolt.

ACTION: On set-back, the striker engages a groove in the centrifugal bolt locking it in place. During deceleration, the striker creeps forward permitting the bolt to move out-ward clearing the central channel. The striker is then free to strike the detonator upon impact.
