M557 or M572 Point Detonating Fuze

The M557 and M572 fuzes (2) have selective superquick delay setscrews. The fuzes are packed

set for superquick and have a booster attached. Premature functioning can occur when fuzes are

fired in heavy precipitation: i.e., rainfall, sleet, snow, or hail. These fuzes can be set to SQ

(superquick) or DELAY action by turning the setscrew. The M572 fuze is identical to the M557

fuze with the exception of epoxy under the steel ogive. The M572 fuze is handled, set, and fired

the same as the M557 fuze.
