6. Toggle Bolts
Toggle bolts, also known as butterfly bolts, are designed for hanging heavy items on hollow walls. They consist of a bolt and a pair of spring-loaded wings that expand behind the drywall once inserted. This anchoring method provides a sturdy and reliable hold, making toggle bolts an excellent choice for mounting heavy shelves. To install, you’ll need to drill a larger hole in the wall, but the added security and weight distribution they provide make them worth the effort. Remember to assess the combined weight of the items that will be placed on the shelves to select appropriate toggle bolt sizes.
- Ideal for heavy-duty shelves on hollow walls.
- Expand behind the wall to distribute weight.
- Secure hold prevents shelf from pulling away from the wall.
- Requires larger holes for installation.
7. Plastic Anchors
Plastic anchors are one of the easiest types of wall anchors to use and can be a suitable choice for lighter shelving applications. They are inserted into pre-drilled holes and provide lightweight support for screws. However, they should not be used for particularly heavy shelves or items. When installing plastic anchors, ensure that the anchor’s weight limit matches the load of the shelf and any items placed on it. They are often used for quick and simple installations where heavy-duty support is not necessary.
- Suitable for lightweight shelving projects.
- Easy to install with a simple drill.
- Best for use in drywall and hollow materials.
- Not recommended for heavy objects.
8. Self-Tapping Screws
Self-tapping screws can make installation easier and faster, as they can create their own hole as they are driven into the material. This characteristic makes them especially useful for various projects where pre-drilling might be cumbersome. They are often used for metal shelving units or when securing wood to metal structures, effectively preventing the need for additional hardware. When using self-tapping screws, ensure you have the right type for the material in use (wood or metal) to achieve optimal results.
