My Brother machine has the same little round thingee and I threw it as far as I could--it is useless. My hands are large and there isn't enough room to even get a hand in the space let alone turn anything. I found a little screwdriver with an offset ratchet handle that works fine for me. Bought a little 1 inch stubby screwdriver from Annie's catalog and it is just about as useless cause I can't get a grip on it to do anything. And if I ever get another machine (not likely) I will be sure there is enough space to get a hand in there to do anything. Live and learn, I guess.
