ABSTRACT:
An improved nail member having first and second heads on a shaft with two ends. One of the ends being defined by the first head and the other end has a pointed termination. A weakened portion is positioned between the second head and the pointed end, substantially closer to the second head. The weakened portion permits a user to readily break off most of the shaft including the pointed end. When the nail member is passed through an opening in an electrical box it keeps it in place while at the same time permits ready detachment of the shaft.
