Klein Tools 32539 10-Fold Screwdriver / Nut Driver, Metric Hex

I bought this tool for HVAC work in commercial kitchens and it is truly fantastic. It folds in itself so that it is compact yet diverse in all the bits and sockets. There are 4 different bits with this two of them being electrician bits so I only use the philips, flathead, and socket options. I was definitely nervous plunging 30 dollars for this tool but I did because it a klein. And once again, i have another klein tool that will give me its value back plus some. ❤️

Handy as all. Heavy duty.

I was looking for a good edc driver option to throw into my bag for unexpected surprises. This thing works great. Unfortunately, it's actually too big and substantial for my purposes, but it is hefty and will get most jobs done. I'd recommend it to anyone who isn't looking for a light carry option.

I bought these because I need a good set of Allen keys on my person while I run around a building all day. These fill that role well. They really could of added a pocket clip to all of these "10 folds" they make. I was turned off of the screwdriver "10 fold" version as the ergonomics isn't all that great from driving long screws, feeling threads, etc. I need Allen keys to make quick adjustments on adjustment screws, possibly removing short bolts on various things so the somewhat awkward ergonomics are really not that big of a deal. You can definitely get leverage on the chunky handle to break open rusty stubborn hex head bolts. The tips are well machined and fit very snugly on all of the sizes I have used so far. The tool is well made and you can feel the quality in every aspect of it. The lock up is very tight with no play and both the lock bars and shaft ends are overbuilt. I cannot see anyone breaking the tool itself. The bits fit inside the sleeves perfectly, not too tight or loose.I plan on drilling and tapping the end of this and adding a pocket clip off an old pocket knife. This would more than likely be too fat to wear clipped to your front pockets but I have other pockets on my pants where this already resides. I feel like that will help it functionally as it won't be bouncing around in my pocket all day. This is a great durable small set of Allen keys with all of the common sizes you need, it's not meant to replace your real set of long arm Allen keys but is great for easily accessible short fasteners/ adjustment screws. I will update this in a few months of everyday use.4/26/17 updateTool has held up very well. Has seen some hard use and has been carried everyday for a good few months. I have added a pocket clip shortly after I got it and it also is holding up well. Note to users thinking of doing this, the red handles are aluminum and drill and tap easily but the actual frame is a VERY hard steel and will snap taps and drill bits like no ones buisness. These also help the tool keep its shape when torquing hard on a fastener. Very solid product from klien. I really feel they should add a pocket clip on all of these models.

Replaced worn out part of appliance, Fit perfectly

Great EDC pocket multi use tool. I appreciate all the different bits and the two different nut driver sizes.

I'm a service tech for a HVAC company. I keep this thing on me with a flashlight and a Leatherman. At all times these are in my tool pouch and this thing really gets me out of jams and saves me trips to the truck. It's a great tool and great quality. I thought it's shape would bother me but it doesn't. I really like this ten in one.

Klein has a history of making quality products and this one is no different. However, there are a couple of issues that need to be addressed.This tool is essentially like having a multi screwdriver in your pocket. Either end has a fold out, lockable, driver with a removable piece that holds 2 reversible screw driver bits. So there are a total of 8 individual screw driver ends available (4 on each fold out). The other 2 tools mentioned in their advertising are the nut drivers, which are simply the sockets where the bits fit in. I would not recommend putting excessive strain on the nut drivers, but for medium duty jobs they should work fine.The one design flaw that I notice is the lack of a pocket clip. This may not a deal-breaker, but it is a little irritating. Due to this, the tool would be perfectly comfortable in a toolbox, but clunky in a pocket.The bad: I am not sure if the quality control issue extends beyond the one that I got, but mine came with a problem. One side of my driver folded out nicely with the right amount of resistance, and clicked into place firmly and securely. The other side was loose when folded up and loose when it opened. Then once clicked into place it was loose there as well. It was still functional, but felt rickety to use. Upon close inspection I discovered that the loose side had not been properly assembled. When i attempted to adjust that side with a separate allen wrench, the extremely low quality screws that hold the tool together easily stripped out and I was unable to work with them. It took some effort to disassemble the entire tool but when I did I found that those 4 screws were really the only low quality parts in the tool. So I went to the hardware store and picked up some higher quality screws and reassembled the tool, making sure to fit the parts together correctly this time. Total cost was somewhere around $2.00 for 4 screws and 4 washers, and about an hour of time. Now my tool functions exactly right with both sides operating firmly and securely. I am disappointed in Klein as they have historically been higher quality than this, but I am pleased that it took only a little extra to get it right.Overall, I am excited to own this tool. I am pleased with the functionality and quality that it now has. I expect to get a lot of useful life out of it and I would recommend it to anyone who is willing to make the same adjustment that I found necessary.
