Abstract: A breakaway nut fastener is provided having a hybrid construction of plastic and metal. The breakaway nut fastener includes a head portion and a nut portion connected by a thin walled section. The head portion is made of plastic and has a shape so as to mate to a tool. The nut portion has an exterior shell having a cavity for receiving a nut insert. The nut portion's exterior shell is made of plastic while the nut insert is made of metal. The breakaway nut fastener's thin walled section is also made of plastic joining the breakaway nut fastener's head portion and the nut portion's exterior shell. The thin walled section is made of plastic, and preferably the head portion, nut portion and thin walled section are constructed as one part forming a single component of plastic.

Abstract: A hybrid stackable fastener is provided for mounting to a substrate having a threaded hole. The hybrid stackable fastener is constructed to support stackable fasteners not having a threaded element. The hybrid stackable fastener has a body having a central bore defining a central axis. The central bore is tapered so as to have a diameter smaller at the bore's proximal end than toward its distal end. The hybrid stackable fastener further includes a bolt having a screw thread which extends distally from the body's central bore. Preferably, the fastener includes a plurality of spokes which radially project from the body so as to support a concentric ring.

Abstract: A stackable fastener is provided for mounting to a substrate having a non-threaded hole or for affixing to similar fasteners. The stackable fastener includes a body having a central bore, and a force member rotatable within the body's central bore. In addition, the fastener includes a plurality of fingers which extend axially from the fastener's body. Rotation of the force member causes the fingers to extend radially outward to lock within a substrate hole or within the central bore of a similar stackable fastener.
