ABSTRACT:
A fastener is described in which a substantially rigid pillar formed at one of its ends with a radially enlarged head is provided with a number of radially projecting and longitudinally extending substantially rigid webs, the fastener being further formed with a number of thin plates arranged between adjacent webs in a plane or planes transverse or oblique to the axis of the pillar, the or each plate being attached at one of its edges to one of the webs, and the radial extent of the webs being less than the maximum radial extent of the plate or plates. The plates can be arranged in planes to which the axis of the pillar is perpendicular, or the plates may be inclined in either the circumferential or the radial direction with respect to the pilar. The head of the fastener may be a simple dished skirt, or may be provided with a formation adapted to retain a second component.
