I think these are called "spanner" bits. The precision drivers from ifixit are pretty good if you need accuracy for working on computers, rc cars, robots, etc. But they're aluminum so not great for heavier jobs. I still use a ratcheting driver or a power tool for anything that requires some effort.

The ironic part is that I have this screw bit, but the screwdriver is far too small to get into that recess and the bit is proprietary to the screwdriver.
Yeah, but that's adding another step to making your stuff less repairable which absolutely shouldn't be the case. Repair should be as easy as possible but that stands against profit, corporations want the devices/items to be only for limited time use and not as long as possible.
