ABSTRACT:
A fastening system utilizes a tapered plug configured to be matingly received in an elongate, buttonhole-like slot. The slot has an enlarged receiving portion into which the tapered plug can be axially inserted, and a narrower retaining portion having a cross-section which tapers in correspondence with the taper of the plug to establish a snug, secure connection. The retaining portion has an undercut end region which matingly engages a maximum of surface area of the tapered plug to establish a connection which will transmit relatively heavy tension, compression and shear loadings as well as bending moments. The plug is preferably molded from plastics material. The slot is preferably formed using a rotating cutter.
