ABSTRACT:
A prewinder apparatus attached to a drive tool to install helical coil inserts includes an adapter attached to the drive tool. A rotatable tubular sleeve in the adapter is engaged with the tool drive and has opposed engagement walls of a longitudinal slot extending through a hollow portion. A mandrel has a threaded first end and a pin transversely extending from a second end positioned within the longitudinal slot. A stop slides within the adapter member and rotatably receives the sleeve. The stop has a plurality of external threads. A stop regulator rotatably disposed in the adapter member has internal threads engaged with the stop external threads. The stop is axially displaceable within the adapter member and infinitely positionable along the stop external threads by manually rotating the stop regulator. A ball or male detent member biased to engage detent cavities of the stop regulator provides predetermined stop axial displacement.
