Nut drivers are used for tightening nuts and bolts. Great for working on cars, trucks, bikes and just about anything else, nut drivers have a hollow shaft that allows you to remove nuts from protruding bolts. They come in different sizes and are made with a heavy duty chrome-plated high carbon shaft. Comfortable handles allow you more than enough torque to get the job done.
