A member (1) for securing insulation panels (7) to a structural component (8) is formed of an annular head (2) and an axially extending hollow shaft (3) extending from the head. The hollow shaft (3) is arranged to receive a nail (9) for fixing the member to the structural component (8). An axially extending section (4) is positioned within the hollow shaft (3) and has an abutment (5) at its end closer to the head (2). When the nail (9) is driven into the structural component (8) its head (2) contacts the abutment (5) and at least an axially extending part (4) of the section is collapsible to compensate for excess driving energy supplied to the nail whereby it is inserted for variable depths into the structural component (8). The collapsible part (4) of the section prevents compressive forces from exercising any damaging effect on the insulation panels (7).
A member for securing insulation panels (7, 25) to a structural component (8,26) comprising a large area annular head having an opening therethrough, a hollow shaft of smaller transverse area than said head secured to and extending axially from said head in alignment with the opening therein, an axially extending section positioned within said hollow shaft and having a first end closer to said head and a second end more remote from said head, said first end forming an abutment, said hollow shaft arranged to receive a nail and said abutment arranged to form a stop for the nail, at least an axially extending part of said section being collapsible between said abutment and the second end of said section, said axially extending part is spaced inwardly from said hollow shaft, said axially extending part is formed as a sleeve,
