Ideal for automotive assembly, small engine repairs, dash and door actuator work, and more, these Low Profile Screwdrivers feature a slim, compact design that fits conveniently in a pocket and the open slot on handle allows you to fasten or secure to a key ring or other device. The 10mm alloy steel bits are small enough to reach into tough access areas, while still affording full engagement to the screw at a 90-degree angle.
