Abstract
A thread protector and seal device, suitable for use with automated shell lling equipment utilizes a flanged semi-rigid tubular member having a plurality of longitudinally disposed slots on one end thereof to facilitate insertion into the nose end of an internally threaded projectile. A compliant member is molded into interior and exterior annular grooves of the insertion end of the thread protector to prevent the accumulation of explosive material from entering the threaded fuze area of the projectile during a loading operation.
