These fuzes differ from the M115 series in that they do not have reduction gears in the vane assembly and therefore arm more quickly. After 18 to 21 revolutions of the vanes, the arming stem, secured to the vane nut by a safety (cotter) pin, is unthreaded from the plunger. The air travel to arm is 100 feet. These fuzes will function on an impact angle of 3 degrees and give positive action because of the cocked firing pin.
The original M112, M113, and M114 series of fuzes used primer detonator M16. This primer detonator was modified to the M16A1, which has a higher shoulder. Series M112 was modified to the M112A1 in order to accommodate primer detonator M16A1.
