Abstract
A prewinder apparatus attachable to a drive tool to install a helical coil insert includes a body connected to the drive tool. An adapter rotates and is releasably connected to the body at operator selected positions. A prewinder portion displaces in/out of the body. The prewinder portion translates into the body until a fastener engaged with the prewinder portion contacts a stop member defining a predetermined helical coil insert insertion depth. A mandrel axially extends from the prewinder portion when the prewinder portion moves into the body to rotatably insert the helical coil insert. A clutch engages/disengages the mandrel from a drive member. A second clutch or a stall device stalls the drive tool after coil insertion.
