An external cladding panel is secured to a building support member using a fastener, in which the fastener comprises a tubular body (1) having a shaft (2) disposed within it. The shaft (2) has a compression member (4) mounted or formed on a distal end and has a rotatable member (7) at a proximal end which, when rotated, serves to draw the compression member (4) in a rearwards direction. The fastener has at least one deformable member (3b-3c-3d) which surrounds the shaft (2) and is disposed axially between the compression member (4) and the tubular body (1). The fastener is provided with engagement means for engaging the building support member. The external cladding panel is secured by :(a)identifying a fastening hole in the external cladding panel or, where there is no fastening hole, forming such a hole;(b) inserting the fastener into the hole from an internal side of the external cladding panel so that the compression member on the shaft and the deformable member protrude through the hole and beyond the external cladding panel and so that the engagement means of the fastener engages the building support member;(c)from a location on the internal side of the external cladding panel, rotating the rotatable member thereby to draw the compression member in a rearwards direction to compress and deform the deformable member so that it expands radially outwardly on an external side of the external cladding panel to a width greater than the hole thereby to secure the external cladding panel to the building support member.
