Types of Drywall Anchors
Drywall anchors are devices used to provide additional support and stability when attaching objects to drywall. They help distribute the weight and prevent the anchor from pulling out of the wall. Here are some common types of drywall anchors:
1. Plastic Expansion Anchors
Plastic expansion anchors, also known as conical anchors or ribbed anchors, are one of the most commonly used types. They consist of a plastic sleeve with ribs on the outside and a hollow center. When inserted into a pre-drilled hole, the anchor expands as the screw is tightened, gripping the drywall and providing a secure hold.
2. Self-Drilling Anchors
Self-drilling anchors, also known as threaded anchors or threaded drywall anchors, are designed for convenience and ease of installation. They have a sharp, self-drilling tip that eliminates the need for pre-drilling. These anchors typically feature a threaded design that allows them to grip the drywall securely when a screw is inserted.
3. Winged Plastic Anchors
Winged plastic anchors, also known as butterfly anchors, have two plastic wings that fold open behind the drywall when the screw is inserted. These anchors provide a wide contact area, distributing the weight over a larger surface and offering increased stability. They are ideal for mounting heavier objects.
4. Threaded Metal Anchors
Threaded metal anchors, such as molly bolts or hollow wall anchors, are more heavy-duty options for hanging objects on drywall. They consist of a metal sleeve with a screw and a toggle or butterfly-shaped spring-loaded mechanism. When the anchor is inserted into the wall and the screw is tightened, the toggle expands behind the drywall, providing a strong and secure hold.
5. Toggle Bolts
Toggle bolts are versatile anchors used for heavier loads. They consist of a long bolt with spring-loaded wings and a toggle nut. The wings are folded to fit through a pre-drilled hole, and once inside the wall, they spring open to provide support. Toggle bolts are commonly used when mounting items like heavy shelves, TVs, or wall-mounted cabinets.
These are just a few examples of the different types of drywall anchors available. The choice of anchor depends on the weight and type of object being hung, as well as the condition of the drywall. It’s important to select the appropriate anchor to ensure a secure and safe installation.
