ABSTRACT:
A wall plug type fastener comprises an elongate anchor body having arm members extending radially from the anchor body. Brace members provide support for the anchor body and permit distribution of load forces applied to the anchor. Anti-rotational flanges extending along the anchor body secure the fastener against rotational displacement when installed in a drywall. The anchor body defines a first axial void in alignment with a satellite body defining a second axial void spaced from and coaxial with the anchor axial void.
