If you are familiar with Klein Tools, you know they are always looking to try and find a way to save you space in your tool pouch. The 65064 is another clever idea to do just that. It combines two of the most popular nut driver sizes, 1/4in and 5/16in, into one driver.

If you need hollow shaft nut drivers, this is not the nut driver for you. However, if you are an electrician, HVAC tech, or anyone that continually runs into 1/4" and 5/16" hex head screws - this nut driver was designed with your convenience in mind. Additionally, like all Klein Tools drivers, they offer the popular ergonomic cushion grip.
