The Toggle Wing Anchor is a four-piece fastener consisting of two matching "wings", each bent at two 90 deg angles. They also have an internally threaded nut with protrusions spaced 180 deg apart which serves as a pivot attaching the two wings. Finally, a wire spring provides the necessary tension to open and close the wings.
Toggle Wing Anchors are light-duty anchors for use in hollow base material applications. They spread the load over a larger area and are more temperature resistant than other hollow wall anchors.
