Manufacturing :
The main body is made of extruded Brass material having 23 spare parts. The main body is finished at CNC Lathe while other parts are made at Single Spindle Auto M/cs.
Role :
Fuze DA No. 162 MK 8 (M2) Empty is direct action detonating type. It is assembled with Bomb 81 mm HE/PWP Mortar with the help adapter tube.
Function :
On firing, the shock of the discharge causes the detent to set back compressing its spring & thus clearing the diagonal channel for the ball to sliding down. The shutter is kept in un-armed position by the point of the striker as also by the frictional force due to set back. The striker also sets back & releases the ball which slides down in the Diagonal channel.

On impact, the impact causes the wind shield to crush down on to the head of the striker which compresses the striker spring & pierces the detonator which comes directly below in the shutter during flight. The resulting detonating waves passes through the septum to the stemmed explosive channel & then to explosive pellet in the magazine to detonate the bomb.
