To provide a bolt supplying and selecting device in which bolts of different lengths are sorted to be supplied to desired bolt sorting passages.

A device is provided with a bolt feeder 21 to supply plural sorts of bolts B of different lengths in a mixed flow condition with shaft parts directed downward, an inflow passage 40 in which the bolts B delivered from the bolt feeder 21 with the shaft parts directed downward, a bolt sort detection sensor to detect a sort of the bolt B, plural bolt sorting passages 71a-71f branched from the inflow passage 40 for the respective bolt sorts, and discharging mechanisms 91a-91f for the respective bolt sorts. The discharging mechanisms 91a-91f have an actuation member 92 which can be freely moved to advance/retract in a crossing direction to the inflow passage 40. The actuation member 92 is changeable among a first condition in which it retracts from the inflow passage 40, a second condition in which it prohibits the movement of the bolt B on the inflow passage 40, and a third condition in which the bolt B is fed to the bolt sorting passage 71a-71f.
