Flux™ Driver. This hex driver functions as a standard screwdriver and as a T-handle driver, depending on where the bit extension adapter is placed. It includes three hex bits (one Phillips, two flat) which each have small ball detents to hold them securely in the driver handle until needed. The Driver's utility is enhanced by a small L.E.D. work light near the tip to light the work space. A Single Chassis Carabiner is included.
