## 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.

## Claims

### Claim 1

A hybrid stackable fastener comprising:
an annularly shaped body forming a central bore defining a central axis, said bore having a distal end and a proximal end, said bore forming an opening at its proximal end with said central bore being tapered to have a diameter smaller at the bore's proximal end than toward the bore's distal end;
a plurality of spokes radially projecting from said body;
a ring concentric with said body;
said spokes engaging and radiating radially inward from said ring to engage said body to form a plurality of hollow slots with the periphery of each of said slots being defined by said body, a pair of adjacent spokes and said ring so that said slots form bores permitting the passage of objects; and
a bolt having a screw thread which extends distally in the direction of said central axis from the body's central bore.

### Claim 2 (depends on 1)

The hybrid stackable fastener of claim 1 wherein said bolt is rotatable within said central bore.
