ABSTRACT:
A wing nut installation clutch drive device and method of installing and removing a hurricane shutter. An elastomeric body includes a bore extending longitudinally therethrough for tightly frictionally receiving a drive shaft, a portion of the length of which is tightly frictionally engaged in the bore wherein a rotational force applied by a drive motor engaged with an exposed portion of the drive shaft is translated to the body. A cavity is formed into a distal end of the body adapted to biasingly engage over a wing nut including the hub and wing members thereof whereby the rotational force is applied to install and tighten the wing nut or to loosen and remove the wing nut from threaded engagement with a threaded shaft of each of a plurality of bolts used to retain the shutter without damaging or over tightening the wing nut. An anti-slip improved bolt head of the bolt is also provided.
