<p>Disclosed is the improvement in a plastic screw socket which comprises a flange designed to be brought into contact with one surface of a given panel and a leg extending perpendicularly from the lower surface of the flange and adapted to be inserted through a matched perforation bored in advance in the panel, the flange and the leg being jointly provided therein with a through hole pierced vertically therethrough from the upper surface of the flange to the lower end of the leg, the leg being divided into two opposed segments by two slits inserted longitudinally therein from the lower end of the leg upwardly, whereby the insertion of a screw from above the flange into the through hole causes the leg to bulge outwardly and consequently come into tight engagement with the inner wall of the perforation in the panel. The improvement resides in having the leg divided into two segments by two slits inserted longitudinally therein in such a way that the lateral directions thereof do not coincide with any of the radii drawn from the central line of the through hole.</p> |
