The Definition of Interrupted Thread
A screw with about half of its threading removed in longitudinal sections. Often used at the breech end of a
takedown firearm's barrel. When the barrel's interrupted female threads are inserted into the receiver's
complementary interrupted male threads, only a partial rotation is necessary for assembly rather than many full turns.
