ABSTRACT:
A fastener assembly in which a fastener is adhesively secured within a borehole. A fastener having a shank with longitudinal channels is inserted within a borehole. A fluent adhesive is forced along the longitudinal channels of the fastener to occupy the space within the bore adjacent to the fastener. The adhesive is permitted to harden in situ so as to provide a strong chemo-mechanical bond.
