Dart with main body has point at front end, and threaded hole at rear end for holding shaft, and threaded pin with flight stabilizer

摘要

The front end of the dart's main body (2) is pointed; the rear end has a blind-hole (2.1) in which is a threaded hole (2,11) into which is removably screwed a shaft (3) joined to a flight-stabilizer by means of an insertion-section (3.1) possessing a threaded pin (3,11). Between the rear end of the threaded hole and the back end side (2,2) of the dart's body, the blind hole has a radially symmetrical stabilizer section (2.12) which grips over a non-threaded section of matching diameter and adjoining the threaded pin.
