5.5mm Hex Nut Screwdriver Socket Driver Hex Nut Key Wrench Screwdriver - Pack of 2

Great tool for what it is. Good Handel. I brought this for an assembly line for 5.5 nuts, been working out.

My robotics team uses these every day. The Rev Robotics part use 5.5 screws. I have bought several because my student keep losing them. I assume the end of the year during cleanup i will have about 20 of these.

Works for a while, but definitely not meant to be used a lot. Some Chinese trash.

These are fairly small and fit into tight places well for FTC robotics stuff if you are using REV 3mm screws, but they aren't good steel and they wear down quickly. Probably not too much of an issue if your kids loose them as quickly as mine do, lol

This driver fills the need for that special tool you need for take off the ignitiion coils of GM vehicles . Gm in it imfinate fate uses 5.5 mm wrench for those pesky bolts on those coils. You just cannot find the tight tool anywhere to remove them if you need to. Also they are needed for some fords late 70's engines systems , Speciial tool salesmen that stop buy my shop want a high price for these tools. Amazon carriers them at much cheaper price

Very fitting and placed inside our Robotic labs

Lightweight
