DESCRIPTION:

This fuze is a simple impact fuze consisting of a striker and attached pressure plate held away from the detonator by a thin aluminum shear wire. A safety cap is screwed over the head of the fuze, and the sides of the safety cap hold a safety clip in position beneath the pressure plate of the striker. The safety clip consists of two metal seg-ments riveted one at each end of a short strip of spring steel.

The detonator is carried in a brass detonator holder screwed into the underside of the body. The channel in the bottom of the detonator holder is stemmed with C.E., and above the holder, interposed between the detonator and the striker is a small brass re-taining disc supported on a washer of similar material.

The magazine consists of a brass cup crimped to the body of the fuze.

OPERATION:

Before firing, the safety cap is removed, and the safety clip is ejected. The safety cap is then replaced, ensuring that the round will not fire on water impact. On impact with a hard surface, the safety cap is crushed, and the pressure plate drives the striker through the shear wire and into the detonator.

REMARKS:

(1) It should be noted that an unexploded round found with the safety cap in posi-tion is by no means to be considered safe, as the safety cap is replaced after the safety clip has been removed.

(2) Mks II* & III: These Marks differ from the Mk II only in that a solid horseshoe shaped metal safety block replaces the spring safety clip assembly.
