A fastener device includes a fastener member having a planar element and
having a tip for engaging into a plasterboard, and an anchoring device
having one or more teeth formed on the planar element for engaging with
the plasterboard and for preventing the fastener member from being
disengaged from the plasterboard. A cutting member is disposed between
the planar element and the tip for facilitating an engagement of the
fastener member into the plasterboard. The planar element may include one
or more reinforcing ribs for reinforcing the fastener member, and an
enlarged head for limiting an engagement of the fastener member into the
plasterboard.
