The Aerosmith Toggle Bolts are drywall and hollow cavity anchors that are specifically designed to be used in drywall/wallboard and other hollow base materials where expansion anchors typically do not work or perform well. The toggle bolt is a two-component system consisting of a machine bolt in either a round, mushroom, or flat head and a spring wing. Sizes range from 1/8” to 1/2” in diameter. A variety of different lengths can be used, depending on the application and thickness of the material, before entering the hollow cavity.
