Your tool bag may just have gotten a little lighter. Rather than carrying five or six different nut drivers, you could instead carry a single Klein 5-in-1 or 6-in-1 “multi-nut” driver to take their place.
The Klein 5-in-1 multi-nut driver offers 5 nut driver sizes: 3/16″, 1/4″, 5/16″, 3/8″ and 9/16″, and the 6-in-1 adds in an extra 7/16″ size.
These multi-nut drivers use a series of different-sized, double-ended steel shafts that nest together, somewhat like the Klein 11-in-1 screw and nut driver.
The 9/16″ nut driver is built right into the classic Klein-styled cushion grip handle.
The largest shaft is extended with a 9/16″ hex bolster, for those times when you need more torque to move a nut.
Although not very striking in online images, the ends of each shaft are color-coded for quick nut driver size identification.
The best prices I could find online were on Amazon. There, you’ll pay $22 for the Klein 32801 5-in-1 driver or $30 for the Klein 32800 6-in-1 driver, both with free Prime Shipping.
I just saw the Klein 5-in-1 driver for the first time last week in one of the Klein tool holiday season bundles at Home Depot. The bundle included the 5-in-1 nut driver, a set of wire strippers, and a pair of linesman’s pliers for around $50.
The other tools in the bundle dint excite me much, but the 5-in-1 nut driver seemed like it was a new solution for not having to carry multiple nut drivers. So when I got home I looked up the tool online and found Klein also made a 6-in-1 version.
Most of the times I need a nut driver, I’m not sure exactly which size I need, so I end up grabbing 2 or 3 different nut drivers to make sure I don’t have to go back to the toolbox. With a tool like this all I would have to do would be to grab the one tool.
I realize these drivers aren’t going to work in every situation. For instance, the driver shaft isn’t hollow, so it will only work in situations where you don’t need to reach a nut deep on threads.
My last thought is that you get seven different openings with the 6-in-1 multi-nut driver, so what are they doing with that last opening?
