Expanding metal wall anchors, often referred to as expansion anchors or toggle bolts, are hardware devices used to secure objects to walls or ceilings. They are constructed from metal and feature a unique design that allows them to expand within the wall when screw tension is applied. This expansion locks the anchor in place, providing a strong hold that can support significant weight.

Nail expansion anchors are fasteners that consist of a metal sleeve and a nail or shank. When installed into a pre-drilled hole, the anchor expands against the wall of the hole, creating a stronghold that keeps the anchor firmly in place. The simple design makes them suitable for a range of applications, from hanging shelves to securing heavier equipment.
