Method of fastening

A method of securing an article to a support, without making a hole in the support, by means of a fastener which can be welded or bonded to the support and, while accommodated in an aperture in the article through which it projects, caused to effect clamping of the article to the support, characterized by providing a fastener comprising a tubular shank and a centrally disposed pin, part of which is accommodated in the shank and part of which projects from the shank at the opposite end of the fastener from that which is to be welded or bonded to the support, anchoring the pin to the shank at a locality remote from the end from which the pan projects so that pulling of the pin against reaction of an anvil bearing on the shank at that end effects deformation of the shank to set the fastener, welding or bonding the fastener to the support with the shank of the fastener accommodated in an aperture in the article and setting the fastener by means of a tool which pulls the pin while pushing on the end of the shank from which the pin projects to set the fastener and cause said article to be clamped to the support.
