The INSTY-DRIVE® System provides a speedy alternative for driving screws and fasteners.
Use an 827/828 Series countersink or an 837/838 Series drill pilot or clearance hole. Then, simply snap the INSTY-DRIVE® extension onto the 1/2" hex collar and insert the appropriate bit into the 1/4" end of the extension to drive the fastener. The system is especially effective when installing many fasteners of the same size. The extension accepts and drives any 1/4" hex power driver bit.
