Point detonating fuzes of M526 series are of the superquick, delayed arming impact type used with 81mm HE and WP Smoke cartridges.
The head of the fuze contains a spring loaded striker, direct acting firing pin, and a clockwork mechanism to delay arming for a safe distance from the muzzle of the mortar. The head is threaded into an aluminum body containing a cylindrical slider to position the detonator, and a booster lead charge. A tetryl booster is threaded into the base, and is covered by an adapter containing additional tetryl booster pellets. The adapter is fitted to the external fuze threads formerly intended for attachment to the projectile, and the exterior of the adapter is threaded to fit the ammunition. Positive safety for shipment and handling is provided by a safety wire and pull wire.
Fuzes M526 and M526A1 differ in the design of the safety and pull wires and fuze nose.
