A drywall anchor, also known as a wall anchor, is an insert that, combined with the appropriate screw, can create a firm mount anywhere on a drywall panel or similar hollow wall. A drywall anchor goes between the screw and the drywall, gripping the drywall much more effectively than a screw would. Some have toggle arms, which either drop into place behind the wall or expand within the cavity. Others include wide threads that carve out grooves in the wall for traction. All drywall anchors are designed to create a firm mount point by distributing the applied load over an increased surface area.
