ABSTRACT:
A fastening device of the invention includes a head, a tool hole formed in the head, and a leg extending downwardly from a lower surface of the head and having engaging portions. The tool hole has at least one opening on a peripheral surface of the head. When the leg is inserted into a hole in a member to be jointed, the engaging portions engage the member. When the fastening device is removed from the member, a tool is directly inserted into the tool hole of the head to pull out the fastening device.
