1. A fastening system for a metallic cellular shipping container floor, comprising:
a potted insert comprising a body disposed between a top flange at one end of the body and a bottom flange at another end of the body, the body defining a channel from the top flange leading towards the bottom flange and having a depth that does not exceed a distance from the top flange to the bottom flange, wherein an interior surface of the channel has a measured perimeter that is greatest at the top flange of the potted insert and is parabolic in progression from the measured perimeter from the top flange to the bottom flange;
a hole formed in a panel of a metallic cellular shipping container floor with a depth that is identical to or greater than a distance from a top portion of the top flange of the potted insert to a bottom portion of the bottom flange of the potted insert; and,
a self-tapping screw disposed within the channel of the potted insert, the screw comprising a threaded shaft with tip at a distal end of the shaft, and a screw head at a proximal end of the shaft;
wherein the tip of the self-tapping screw and at least a portion of the threaded shaft are embedded in a cross-beam member abutting a surface of the panel; and,
wherein the self-tapping screw secures itself into a top portion of the cross-beam member with a head of the self-tapping screw contacting the surface so as to pull the potted insert and the metallic cellular shipping container floor along with it towards the surface of the cross-beam member.
