Applicable scene:
1.Do you find that when you want to replace the chain wheel studs, if you just use a hexagonal wrench to screw the chain wheel studs, that they also slip and rotate?
With this wrench to clamp the slotted slot of the main disc nail, the disc nail can be easily unscrewed.
2.At the same time, when you want to tighten the disc nails, but find that the disc nails also slip and rotate, is it extremely crazy? With this tool, the problem can be easily solved.
3.9\10mm hexagon socket to solve the tightness of small screws such as V brake.

Matters needing attention:
Every tool has skills to use. When using it, you must think about skills to avoid hurting your hands.
Use this card to screw the main screw, and use a hexagonal wrench on the other side to screw the screw. Remember not to use this tool to force, otherwise, you are doomed to be scratched by the teeth of the toothed disc.
