In order to tighten the fuzes to the projectiles, and set times on the various time fuzes, a number of wrenches, and setters were used. The simplest device was the M16 J wrench. It could be used to tighten rounds to projectiles, and even used to set times on the fuzes, although this practice was frowned upon by command. A fact known all too well by this webmaster. The M18 fuze wrench was the workhorse. Used to tighten fuzes to the rounds, the handle also had a straight slot screw driver that was used to set the PDSQ fuze to delay.
