Convoluted thread: a thread with removal of the incomplete thread at the starting end. This is a feature of the threaded parts that are repeatedly assembled by hand, such as hose couplings and thread gages, to prevent cutting of hands and crossing of threads. Also known as Higbee cut or a blunt start thread.
