Disassembly and Re-assembly

Both of the identical tools are required to disassemble the hinge. Since the assembled screws provide a rotational center for the temple, using only one tool rotates both screws. Therefore, one tool should be placed in the lower screw and held firmly, while rotating the top screw counter-clockwise with the second tool.

Once the top screw has been removed, the tip of the tool can be used to push the remaining nut downwards and out of the hinge block. A note of caution: the screw and nut are small, these steps are best done just slightly above a work surface to prevent the parts from bouncing around and getting lost.
