1. I have personally tested it and found it very effective. The model includes M2.5, M3, M4, M5, and M6 hexagonal wrenches. For small nuts that are inconvenient to pick up or install, using the wrenches in the model can effectively solve these problems and avoid the nuts falling to the ground when removing or disassembling screws;

2. There are corresponding thread size markings on the surface, making it easy to select the appropriate wrench;

。 3. There is a space-avoiding structure in the middle of the screw for the direction of screw tightening, and all the spaces are larger than the diameter of the corresponding screw rod.
