螺絲 - 超小型，堅固

The twist-in mechanism is surprisingly smooth and the firm texture gives exactly the kind of pressure I was craving. After a long night, this little screw really delivers on its promise.

I was a bit skeptical about the firmness, but the precision head on this screw really locks in place and holds steady once twisted. It's surprisingly sturdy for such a small size.

The firmness is just what I needed, and the smaller size makes it surprisingly easy to control during use. That twisting motion really lives up to the name.
