HSP Racing nut drivers feature an all steel construct and have been nickel plated to perfection. The nickel plate process boosts the steel hardness level to a whopping 70 plus Rockwell, the same as automotive grade tools! On the surface you will notice these nut drivers are stubbier than traditional drivers, this characteristic allows for a better overall weight balance and reduces tool box space. A special color coded ring and etched sizing on the shank make it easy to know exactly what size nut driver you are grabbing. The drivers also feature a slim hex wall and deep bore to ensure that you are able to get into the tightest of places and not worry about bottoming out on anything in the process!
