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. At a glance you will be able to know exactly what size nut driver you are grabbing as each one has a special color coded ring and etched sizing on the shank. 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! And as always, 100% Made in the USA!
