7pcs Hex Screw driver, RC Screwdriver Tools Kit Set (0.9mm 1.27mm 1.3mm 1.5mm 2.0mm 2.5mm 3.0mm) for RC Model, Helicopter, Bench Work, Precision Engineering

Very bad product down not fit any screws

The tip of this hex driver is solid and durable. It seems like high-carbon steel was used, and the tip doesn’t bend even if you apply a lot of force on the hex screw.

I am on my second 3d printer and I got tired of using the L shape hex keys. I got these screwdriver shaped keys. I really like them. They are easy to use and very durable. I will not give them up. They are very well made. I use them all the time and they stand up to my abuse.

Must have tools

Tipically when I have purchased a small sized budget hex it typically does not fit right and gets returned or tossed in the trash. Happy to say that I was very pleasantly surprised with the fit and finish of these Hex drivers. I used the 1.3mm on some small bolts and it fit perfectly without stripping them like other one drivers that I tried. I was even able to remove some 1.3mm bolts that were partially stripped- that is how nicely these are made. The one minor nitpicky think, is that the plastic cap at the top tends to fall off and it does not rotate in your palm like some higher prices drivers. It’s not a big deal to me, but though it would be worth mentioning. These are a great set of drivers for the price
