Wall anchor for a screw, and assembly constituted by such a wall anchor and screw |
摘要 |
A wall anchor (1) has a head shaft (5) and a screw nut shaft (6) on the same longitudinal axis (4), connected to each other by a plurality of approximately longitudinal small bars (7). The bars (7) are plastically flexible in a direction away from the axis (4). The screw nut shaft (6) is equipped with teeth (18) of generally triangular shape. The teeth (18) form a longitudinal projection with respect thereto and converge on the axis (4) to define a point (22) to perforate or drill a partition (8).
