System for fastening parts

A system for fastening parts, comprising:

• a through hole forming device configured for selectively forming variable width through holes on each of two parts to be fastened from a first surface to an opposing second surface, such that the width of each through hole on the first surface is larger than the width of the through hole at the opposing second surface;
• opposing first and second platens configured for selectively urging the second surfaces of the two parts into engagement while the through holes of the two parts are in fluid communication with each other;
• and
• a flowable material injection system comprising a source of flowable and hardenable material, a flow passage through the first platen and in fluid communication with the through hole on the part engaged by the first platen, and a pressurizing mechanism for urging the flowable and hardenable material through the flow passage and into the first and second through holes between the first and second platens under pressure, and selectively maintaining pressure while the flowable and hardenable material hardens within the through holes.
