Dynamite Nut Driver: 5.5mm

I used to repair printers, this tool made things a lot easier.

I needed a nut driver of a difficult to obtain size (5.5 mm) to be used in a very confined space, in the hub of a scale model wheel. I wondered if it would fit. It happens to be a perfectly slender tool, so it fits more than sufficient.

I got this to adjust some bolts on my 3D printer & it works as advertised. The quality is good & it seems like it will last for many years.

Bought this small nut driver for one specific purpose. We have a large koi pond and it uses an aerator 24 hours a day/7 days a week. It has two diaphragms in it that must be replaced once a year. Inside the machine is a 5.5 nut and it's a hassle every year to try to find my nut driver. This little tool is small enough to store in a Ziplock bag with all the other pieces to our aerator. No more hunting around for the 1 time a year needed tool! Best cheap purchase ever!

Another reviewer mentioned that he bought this to take apart his IBM model M keyboard; I bought it for the same reason, and it works perfectly. The top red part is on a spindle, so you can apply pressure on it while turning the black and chrome body beneath it. Also, note that 5.5mm is very close to 7/32"; it may well work on nuts that size as well.Shipping was fast and the tool arrived less than 48 hours after I ordered it.

I bought this so that I could remove the cover from my Unicomp New Model M keyboard and clean it out. The tool works as expected, and I found a few of my cat's long white whiskers inside.

Good quality and price!

Decent quality tool.
