Molly bolts sizes: #10, 1/8, 3/16 and 1/4 inch. Lengths: short and long.
Molly Bolts are used in wallboard, plaster, paneling, doors, and other soft, hollow base material. A molly anchor works by expanding its legs after being inserted through a pre-drilled hole and tightened with the screw on the head of the anchor. This pulls the legs flush to the back of the wall and the head flush to the object you are securing. Fixtures can be removed and replaced without need to replace an anchor. Steel with zinc plated finish.
