A method is described of securing a blind fastener (10) in a composite material (40, 42) comprises the steps of forming of hole (48) in an outer wall (40) of the composite material, subsequently inserting a liquid adhesive (50) through the hole (48) so as to fill a chamber (44') formed in the material behind the hole, then inserting a blind fastener (10) through the hole into the liquid adhesive until the head of the fastener (14) engages with the composite material wall (40), subsequently deforming the blind anchor (62) into engagement with an inner surface of the outer wall (40) to support the blind fastener (10) in the liquid adhesive while it sets and, in particular, for the liquid adhesive to engage with at least one channel (64) formed in the circumference of the fastener. <??>There is also provided a blind fastener for use in such method which comprises an elongate hollow body having an enlarged head (14) and a deformable weakened region (28), in which the body has, remote from the weakened region (28), at least one adhesive receiving channel (64) formed in the outer surface thereof. <IMAGE> |
