This faster attaches the derailleurs hanger to a Giant Stance 2 and is located on the inside of the arm. The bike is equipped with Shimano Diore 10 speed.
Is there a proper tool for this faster? Not have much luck with a screw driver due to the width (~10mm). If yes, what is it called?
Also, what ways are you guys changing these out without proper tools?

It looks like a chain ring nut tool would be correct.
it probably is but not for everyone I’m pretty sure it’s a part that doesn’t get taken out much so it only gets put inside when the bike is assembled and a machine does that. Maybe try to make a 3d printed tool for it? Not an expert but u can give it a try
Park Tool CNW-2C Chainring Nut Wrench is what you’re looking for 🙂
Old chisel to hold it while you screw from other side ,but I bet park tool have a specific tool and I bet it’s in blue
Thumb, usually.. once it catches each other it tightens nicely..
Worst case scenario, small flat screwdriver to hold it.
No fancy tools here.
You’re not meant to use a tool on it, it just sits inside and you use a 5 mm Allan key from the other side to tighten it up
Friction will do a fine job while you turn the Allen key in the other half
I usually use my fingers
I just use a wide flat blade screwdriver.
I fucking hate these fasteners. Glad that modern chainring bolts have a hex slot on both sides. Surprised this was the standard for so long.
Standard screwdriver or a quarter.
You can usually get them started and then proceed, if it’s spinning endlessly I usually go for a basic butter knife then I’m good to go.
Yes, but they suck. Your best bet is a very wide flathead screwdriver
