Design

The M67 grenade has a spheroidal steel body that contains of composition B explosive. It uses the M213 pyrotechnic delay fuze.

The M67 grenade weighs in total and has a safety clip to prevent the spoon on the grenade from being triggered in the event the safety pin is accidentally pulled.

The M67 can be thrown from the standing position by the average male soldier. Its fuze delays detonation between 4 and 5 seconds after the spoon is released. Steel fragments are formed by the grenade body fracturing and have an injury radius of and a fatality radius of , though some fragments can travel as far as .
