A fastener for securing plywood to sheet metal comprises a head, and a shank with three distinct segments . The first segment is a threaded tip segment; the second segment is unthreaded and has a length which is about equal to the thickness of the plywood; the third segment is threaded and extends from the unthreaded second segment to the fastener head. In use, the unthreaded second segment rotates freely in the plywood without jacking or lifting the plywood.
Dispositif pour fixer le contreplaqué à la tôle comprenant une tête et une tige constituée de trois segments distincts. Le premier segment est un segment à bout fileté; le second segment n'est pas fileté et sa longueur est à peu près équivalente à l'épaisseur du contreplaqué; le troisième segment est fileté et s'étend depuis le second segment non fileté jusqu'à la tête du dispositif de fixation. Lorsqu'on enfonce le dispositif de fixation, le second segment non fileté tourne librement dans le contreplaqué sans faire soulever ou relever ce dernier.
