KLEIN TOOLS32807MAG 7-in-1 Nut Driver, Magnetic Driver has SAE Hex Nut Sizes 1/4 to 9/16-Inch, Cushion Grip Handle for Added Torque

Klein always has great craftsmanship and are innovative in design. I use it daily in Industrial Maintenance field. I highly recommend for anyone. The magnet is extremely strong.

Love this tool! Love that it’s hollow. Great product, durable and great to have different sizes in on tool.

Klein innovation! Works great for Easy to access bolts and nuts. Pass through is nice for long threads. Standard one size pass through nutdrivers are still a superior option. But this still has a place on my smaller grab and go service pouch around the shop.

You can't go wrong with Klein tools.

There are a lot of things about this tool that seem poorly documented.- The slime: I got this tool and when I opened the package it was covered in an unpleasant slimy/sticky substance somewhat like the stickiness you find in very old plastic that is coming apart. It cannot be removed with alcohol, by simple wiping, or with soap and water. I actually returned my first one thinking this was a mold release that had interacted with the plastic packaging. It turns out Goof Off will remove it and simply leaving it out in the open also seems to lessen the stickiness over time (days to weeks).- The shallowness of the drivers: Each driver has a magnet inside to more easily hold a nut you are fitting to a bolt somewhere. This makes most of the drivers very shallow. The thing is that the magnets are open cylinders and can be (carefully) removed. The plastic piece that holds them in the driver can then be removed and several but not all of the drivers turn into deep sockets. The plastic can be put back in if you need that function. Pulling the magnets and then the plastic is tricky and should be done in two steps but it is a simple pull, not unscrewing, unlatching, etc. The tricky bit will be getting a piece through the cylindrical magnet and grabbing onto the opposite side so you can safely pull.- The size: This is a big tool. Think of it as comparable to the biggest screw driver you own or larger. With all the different sizes it is quite handy and takes up less space than an equal number of sockets or nut drivers but don't expect anything petite. It will still fit in the average sized hand.I'm giving it 4 stars because the stickiness is a sign of a quality issue of some kind and the lack of instructions required me to work out the answers for myself. I still think it will be quite useful in my car/emergency tool box and I might even pick up another for the general toolbox.*edit: I don't mean to soak it in Goof Off! Just the old towel and wipe down and test it first as usual. I have no idea how old my bottle is and the volitiles might be gone.

Son in law is an electrician and uses this often. Love the quality of Klein tools!

This set is great for most situations in many different trades. I personally don't use the largest part of the set which is multiple flip sockets that are too bulky for my own needs, and I doubt very many of us could manage loosening or adequately tightening the 9/16" or 1/2" without the wrench assist hex flats built into the handle - if you don't mind also packing a wrench or adjustable wrench. I normally keep the largest part of this set in a drawer near my sockets, and usually use my socket set or wrenches instead for 1/2" & 9/16" applications. I'm sure some trades would find this larger part of the set more useful than other trades. I use the smaller 3 multi drivers in this set almost daily. Sometimes the shafts are too thick to fit into tight spaces so I still need to keep a normal #2 Phillips and a normal flat screwdriver along with this set. I always have the smaller 3 multi drivers in this set with me while working and would never consider working without them as they are very useful, convenient, and durable.The heavy duty 1/4" never wears out, but the 5/16" can get worn out after extensive use. The hex bits last a very long time. Getting the 5/16" to last as long as the 1/4" would make these great multi bit tools even better.One tip of mine is using a 5/16" wrench for extra turning force leverage when using the #2 Phillips multi bit, and you can use other size wrenches with some of the other multi bit sizes.

Works good very functionable
