A fastener for panels, comprising a basal body provided with a flange portion having a circular perforation bored in the central portion thereof for permitting insertion therethrough of a screw and with a pair of legs extended downwardly from the lower surface of the flange portion so as to be opposed to each other across the line drawn perpendicularly through the center of the circular perforation, and a screw receiving body disposed between the opposed legs, provided in the upper portion thereof with a pair of receiving pieces protruding sideways out of the openings formed between the opposed legs and further provided with a screw receiving hole in the axial portion coinciding with the perpendicular line drawn through the center of the perforation. The screw receiving body is provided with engaging protuberances one each on the lateral surfaces thereof opposite the legs and the legs are provided with oblong guide holes adapted to receive the engaging protuberances. The work of setting the engaging protuberances into sliding engagement with the oblong guide holes and tightening a screw inserted past the perforation of the flange portion into the screw receiving hole of the screw receiving body causes the receiving pieces of the screw receiving body to be slid in the direction of the flange portion of the basal body and thereby enables a panel to be held fast between the flange portion and the receiving pieces or panels one each between the head of the screw and the flange portion and between the flange portion and the receiving pieces. |
