Screw anchors

Screw anchors are used to fix objects to walls where screws do not work effectively. A common type of screw anchor, which is used for plasterboard walls (drywalls), is called a drywall anchor. It is a plastic tube.

A drywall anchor    is inserted in a predrilled hole in the wall, and then a screw is set in it. As the screw is driven into the anchor, the anchor expands inside of the wall, and it is secured to the wall.

*drywall anchor (AmE) = wall plug (BrE)
