Abstract
A twist-lock anchoring fastener comprises a head (), a shaft (), and a lance (). The foot is adapted to penetrate through wallboard (). The shaft length is approximately equal to the thickness of the wallboard so that when the foot lies on the back side () of the wallboard and the shaft is rotated, the foot is captured behind the wallboard, completing installation of the fastener. An optional footer () for the head contains raised lines () or bumps () or both to aid in seating the fastener on the wall. An optional wall plate assembly () further strengthens the installation of the fastener by locally reducing pressure within the wallboard. In an alternative embodiment, the fastener comprises a wall anchor that accepts a pin (). In another alternative embodiment, the fastener is designed for installation in our prior-art wall anchor ().
