An attachment member (1) for securing very thick panels to a receiving material, such as a structural member, is formed of an axially elongated cylindrical shank (2) having a tip (3) at its leading end and a flange-like head (4) projecting laterally outwardly from the shank (2) at its trailing end. A contact pressure element (6) is located in the trailing end region of the shank (2) and is axially displaceable relative to the shank. An axially extending part arranged about the trailing end of the shank is arranged for absorbing excess energy applied to the attachment member. The shank (2) is laterally enclosed by an axially extending cylindrical sleeve (7) extending in the range of approximately +E,fra 3/4+EE to +E,fra 9/10+EE of the axial length of the shank. The sleeve (7) has an outside diameter (a) in the range of 1.4 to 3 times the diameter (s) of the shank (2). The sleeve (7) has a trailing end arranged to axially support the contact pressure element (6).
