Abstract
A removable hollow-wall anchor for fastening machine screws to a wall is disclosed. Commonly called a Molly bolt, in one aspect of the invention the head of the Molly bolt is unthreadable from the anchor part of the Molly bolt so that once the Molly bolt has been secured to the wall the head can be unthreaded so as to remove it from the outer surface of the wall. A gripper is used in conjunction with the head to prevent rotation of the Molly bolt when the machine screw is being threaded in or out. The gripper is also removable from the wall. Once the machine screw, head and gripper have been removed from the wall, the outer surface of the wall is flush and free from any part of the Molly bolt.
