large aluminum cross clamp

According to  the marks on the die casting tool, these two large aluminum cross clamps may appear to be the same size, and both are large cross clamps. But they are not exactly the same: they have the same height and the same clamping diameter, but the actual clamping diameter and bearing capacity of one of the transverse clamps is larger. This is due to the fact that the thread diameter is different, and the diameter of the screws at the two ends is naturally different. The threaded hole diameter of the metal screw on the right is 7mm, while the threaded hole diameter of the bolt corresponding to the large round plastic nut on the left is only 5mm.
