ABSTRACT:
A device for confirming the presence of thread in nuts and other threaded parts has a threaded gage mounted on a holder which is connected through a clutch to a motor. The motor drives the holder to rotate the threaded gage to engage the threaded part. Switches are provided to stop and reverse the motor. The device identifies parts without threads and also damaged and incomplete threads. The device does not impart undue force levels to unthreaded, undersized parts or defective parts. The device confirms threads in threaded blind bores.
