This metallic colored detonator consists of a No.8 non-electric blasting cap and a KV-11 percussion cap assembled into a threaded metallic or plastic adapter.
The detonator is screwed into the base of standard Soviet mine fuze (
MUV and MV-5 pressure fuzes).
Upon impact, the percussion cap creates a flame that ignites the flash charge of the blasting cap.
The primer charge is then ignited, detonating the base charge.
The usual method of packaging is 18 detonators per cardboard box.

Length: 60mm.
Diameter adapter 15mm.
Diameter detonator 6.85mm.
