The tapping Blind Joint Parts is used to fasten the screws while tapping.
It requires a lot of force because the aluminum is cut while it is inserted and fastened. A Torx bit is used instead of an electric drill bit to fasten the screws.
In addition, to fasten two aluminum frames in an L shape, a wrench hole is required in one of the aluminum frames. It
can also be fastened in a T shape by specifying a wrench hole in a specified position.
