| Description: |
|---|
| The grenade body is a 2.5-inch diameter steel sphere which is designed to burst into numerous fragments when detonated. The grenade body contains 6.5 ounces of high-explosive, Composition B. Each grenade is fitted with a fuze that initiates the explosive charge. The M33 grenade used the M213 fuze which is a pyrotechnic delay-detonating fuze. It will function the grenade 4 to 5 seconds after release of the safety lever. The body of the fuze contains a primer and a pyrotechnic delay column. Assembled to the body are a striker, striker spring, safety lever, safety pin, pull ring, and a detonator assembly. The M213 fuze is equipped with a steel safety pin and pull ring. The split end of the safety pin is either spread approximately 40 degrees or diamond-shaped to prevent accidental removal and arming during shipping and handling. The pull ring is provided to facilitate easy removal of the safety pin. The M33 grenade is the same as the M67 grenade except that it does not have a safety clip. |
| Use: |
|---|
| The M33 fragmentation hand grenade is used to supplement small arms fire against the enemy in close combat. The grenade produces casualties by high velocity projection of fragments in a uniform distribution pattern. |
| Functioning: |
|---|
| Removal of the safety pin permits release of the safety lever. When the grenade is thrown, the striker assembly, through action of the spring, throws off the safety lever and impacts the percussion primer which functions the primer charge. The primer charge ignites the delay composition which will burn approximately 4-5 seconds. Upon completion of burning, the delay composition sets off the detonator which ignites the main explosive charge and detonates the grenade. |
