It is used for the drain of the large two-wheel carburetor of Kawasaki. Because genuine tools are pretty expensive, substitute here. The length was quite long, and it arrived without problem even for large two-wheelers.
It is 3mm that I bought and it is considerably thin, so it will cause a lot of screwed ends. It is natural, but it is not suitable for high torque.
However, we have been very satisfied because we have found only a long and affordable product so far.
I was satisfied with the impression I used because I was looking for thin and long things. Since I do not use it many times a year, I thought that it would be nice to have a cheaper one with T-shaped metal bare, without "a high-grade acetate resin handle that feels good". .
