This fuze consists of a brass body, an aluminum striker assembly, and a detonator held off the striker by a thin brass shear wire. The striker is held from moving down by three small lugs at the top which rest in gooves at the nose of the fuze body. Also at the top, there is a split ring which keeps the striker in place. The fuze portion which threads into the projectile is very similar to that which is used for Nose Percussion Fuze M10. This particular fuze was found to have been used in many of the projectiles for which the M10 or M17 were generally used. The detonator holder has a small charge of black powder in order to obtain a greater flash to the booster. There are no setback or centrifugal safety features connected with this fuze.

This fuze was called an instantaneous type by the Italians. On impact, the striker is for-ced to the rear, thus shearing the lugs and shear wire. The striker is forced onto the de-tonator, which also moves toward the striker.
