The Tekton Spinner Handle is a universal screwdriver and nut driver that expands the usability of your existing 1/4 inch drive tool systems. The handle's three-sided geometry provides the leverage you need to generate high turning force by hand. Round sections at the front and back ends of the handle create an ideal shape for quickly spinning long fasteners. The overmolded grip is permanently bonded to the handle and won't degrade or become sticky over time. The drive size is printed on the end of the driver for easy identification.
