Rather than carrying around a bunch of nut drivers, carry only one with Klein’s Drive-A-Matic. As you place the driver over the fastener and turn the head, it automatically adjusts to the head of the fastener.
The Drive-A-Matic can fit 15 different nut and hex head screw sizes from 1/4″ to 7/16″. Klein chrome plates the 7″ hollow shaft driver for a smooth finished look, and uses the same black and yellow cushion grip that you’ve come to know and love.
You can find the Drive-A-Matic fro $25 to $43 depending on where you shop.
