TEKTON 5.5 mm Nut Driver

One-of-a-Kind Handle: The patented handle design offers a versatile combination of torque and speed. Its three-sided geometry engages the structure of your hand, not just friction against your skin, to turn the driver. This means you can comfortably apply much more force, even when your hand is greasy or tired. For long, finely threaded fasteners common in electrical, installation, and assembly work, round top and bottom sections allow your fingertips to spin the driver quickly and smoothly. 6-Point Socket: Made to exacting tolerances, the 6-point socket snugly fits hex-shaped fasteners so it won’t slip off while you work or round off corners under stress. A recess inside the shaft accommodates the excess threaded tail of longer bolts or studs. Protective Finish: Rather than a layer of plating, the steel surface of the blades is directly treated with a hot black oxide finish—the same process used to protect firearms. Since this finish can’t flake off, it won’t damage your work or diminish the precise fit of the socket over time.
