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.

A fastener in which a fluent adhesive is introduced for fastening material, said fastener comprising: (a) a solid shank having a leading end and a trailing end; (b) at least one peripherally longitudinal channel along said shank; (c) a head on said trailing end of said fastener; (d) an axial cavity

A fastener in which a fluent adhesive is introduced for fastening material, said fastener comprising: (a) a solid shank having a leading end and a trailing end; (b) at least one peripherally longitudinal channel along said shank; (c) a head on said trailing end of said fastener; (d) an axial cavity through said head defining a mouth, an axially extending sidewall and an inner end; (e) apertures through said sidewalls, said apertures communicating with said at least one longitudinal channel for introducing adhesive through said head and into said channel; and (f) at least one longitudinal flat surface extended along said shank from said trailing end to said leading end, said channel being formed in said flat surface.
