PROBLEM TO BE SOLVED: To provide a non-defective article and defective article decision and supply device which decides non-defective articles and defective articles of exact lengths in spite of any combinations or any shapes of threaded articles. SOLUTION: This non-defective article and defective article decision and supply device for the threaded articles is constituted by arranging a housing member 20 which is freely movable and has a housing hole 21 communicating with a supply hose 13 for guiding the threaded parts 1 into a main body block 2 closed at both ends, providing this housing member 20 with a sensor 5 for deciding the presence or absence of the threaded parts 1 and the normal/defective condition of their height and further, forming a non-defective article discharge port 16 on one side and a defective article discharge port 17 on the other across the extended central line of the supply hose 13 at the main body block 2 on the opposite side across the housing 20. As a result, the simple and exact decision of the non-defective articles and defective articles is made possible even if spring washers are built onto the threaded parts or even if the threaded parts are countersunk screws. The always exact decision is made possible regardless of the inclination directions of the threaded parts as compared with the device for deciding the non-defective articles and defective articles by supplying these parts in alignment on chute rails.
