Screw anchor
From Wikipedia, the free encyclopedia
A screw anchor is a fastener that can attach one object to another in situations where screws, nails, adhesives, or other simple fasteners are either impractical or ineffective. They are often called "toggle bolts," "toggles," "molly screws," or "molly bolts." Anchors can be made of plastic or metal; different types have different levels of strength and can be used on different types of surfaces.
