- Anchors can be used with various dimensions of screws. A small hole is created first with a drill, and some anchors are self-starting. This allows heavier objects to be placed almost anywhere. You can purchase anchors and screws in sets or individually (see Resources below).
- Wall screws and anchors are used to hang objects on walls. This includes very heavy items like mirrors, pictures, plants or bookshelves. The anchors are fastened to the wall screws to strengthen the hold. They are utilized when other fasteners are not sufficient to hold the item.
- Anchors come in two types: expansion and hollow wall. Expansion anchors are used for hard materials. This includes wood, metal, mortar, brick and concrete. Hollow wall anchors are used for hollow walls or thin materials. This could be drywall, plaster or similar material. Hollow anchors will not work in hard materials.
- Expansion anchors can be purchased in various sizes and styles. The bigger the size, the larger the screw it utilizes. The strength increases with the size. Threaded drywall anchors are self-starting and are available in metal and nylon. Winged plastic anchors cost less than metal ones. Toggle bolts are hollow wall anchors that are made of up machine screws and toggles; it is the strongest anchor (see Resources below).
- The size and weight of a mounted item are important factors. The specific type of wall must be taken into consideration also. Each anchor is designed to work for precise circumstances (see Resources below).
