| Description: |
|---|
| The fuze has a brass or steel body containing the firing pin and a spring-loaded sleeve assembly. A resistance ring holds the tiring pin at the rear of the sleeve and away from the detonator prior to firing; there are no bore-safety provisions or external safety devices. The detonator is housed in a brass detonator holder forward of the firing pin. A brass or steel cap and aluminum washer close the forward end of the fuze. A hole is provided in the closing cap to allow detonator flashthrough. |
| Use: |
|---|
| Base Detonating Fuze M58 Practice is used with target practice cartridges for 37mm subcaliber guns. |
| Functioning: |
|---|
| Setback from weapon firing forces theresistance ring back over the shoulder of the firing pin and into a groove near the back ofÂ’ the firing pin, locking the pin in a more forward position in the sleeve. During the flight of the projectile, the combined firing pin and sleeve assembly is held out of contact with the detonator by the sleeve compression spring. Upon impact, inertia of the sleeve and firing pin overcomes the spring and drives the pin into the detonator. |
