Wall Anchors vs. Screws: When to Use Which for a Secure Mount
In this blog post, we’ll explore the differences between wall anchors and screws, and guide you on when to use each to achieve the best results.
When it comes to mounting items on your walls, choosing the right fastening method is crucial for ensuring both security and stability. Two of the most commonly used mounting solutions are wall anchors and screws, each with distinct purposes and applications. But which one should you use for a secure mount?
What Are Wall Anchors?
Wall anchors, also known as drywall anchors or plug anchors, are devices used to provide a more secure hold in drywall or other materials that might not naturally support screws alone. They expand or grip the wall as the screw is inserted, providing additional support for heavier items that might otherwise pull out of the wall. Wall anchors come in various types, including plastic, metal, and toggle bolts, and are ideal for securing heavier objects, especially when you can’t mount directly into studs.
What Are Screws?
Screws are threaded fasteners designed to bind materials together. When used alone, screws are most effective when driven into wall studs, where the material is stronger and can hold more weight. However, screws can also be used in combination with wall anchors when the wall material alone isn’t strong enough to support the load. Screws come in many sizes and styles, depending on the application.
Wall Anchors vs. Screws: Key Differences
Support and Load-Bearing Capacity
- Wall Anchors:
When you need to hang something heavy on a wall that doesn’t have a stud in the ideal location, wall anchors provide the necessary support. Wall anchors distribute the weight over a larger surface area of the wall, which helps prevent the screw from pulling out. This makes them essential for securing items to drywall, plaster, or masonry where studs aren’t accessible. - Screws:
Screws are stronger when driven directly into studs because they anchor into the solid wood or metal behind the drywall. This allows screws to bear more weight without needing the additional support of a wall anchor.

Installation Process
- Wall Anchors: To install a wall anchor, you first need to drill a hole in the wall, then insert the anchor into the hole. Once in place, you can insert a screw into the anchor. As the screw tightens, the anchor expands, securing it firmly in the wall. This process is slightly more involved than simply driving a screw into a stud.
- Screws: Installing screws is a simpler process. If you’re mounting directly into a stud, all you need to do is drill a pilot hole and then drive the screw into the stud. It’s faster and easier compared to using wall anchors, but it requires that you have access to a stud.

Applications
- Wall Anchors:
Wall anchors are ideal when you don’t have access to studs or when you are mounting on materials like drywall, plaster, or masonry. They are perfect for light to medium-weight items such as small shelves, pictures, mirrors, and TV mounts. - Screws:
If you’re mounting something heavy, like a large TV, shelves, or cabinets, and you can access the studs, screws are the best option. Screws provide a stronger, more direct hold when mounted into studs, making them ideal for heavy-duty applications.

Versatility
- Wall Anchors:
Wall anchors are versatile and can be used for a variety of wall types, including drywall, plaster, and even masonry. Different types of anchors, like plastic expansion anchors or metal toggle bolts, can be used depending on the wall material and the weight of the item being mounted. - Screws:
While screws are essential for securing items into studs, they are less versatile than wall anchors when it comes to non-stud mounting. Screws alone won’t work well in drywall unless you have an anchor in place.

When to Use Wall Anchors
Wall anchors are best used when:
- You don’t have access to a stud:
When you’re unable to mount directly into a stud, wall anchors help distribute the load across the surface of the drywall, providing more support than screws alone. - Mounting lighter objects:
Wall anchors are ideal for mounting items that aren’t too heavy but still need extra support, such as small shelves, artwork, or mirrors. - Mounting on drywall or plaster:
When mounting on materials that lack the inherent strength of studs, such as drywall or plaster, wall anchors help ensure a secure mount.
When to Use Screws
Screws are the preferred choice when:
- You can access studs:
Screws directly into studs provide the strongest and most secure hold. Always try to mount heavy objects like large TVs or cabinets directly onto studs. - Mounting heavier items:
If you’re mounting something heavy, such as a large TV or bookshelf, screws into studs are your best bet for maximum security. - Speed of installation is a priority:
When time is of the essence, mounting directly into studs with screws is quicker than installing wall anchors.
Conclusion
In the battle of wall anchors vs. screws, both have their place in the world of home mounting. Wall anchors are the go-to solution when studs aren’t available, providing a secure hold for medium-weight objects. On the other hand, screws are your best option when you can mount directly into a stud, offering the highest load-bearing capacity.
By understanding the differences and knowing when to use each, you can ensure your mounting projects are secure, whether you’re hanging a small picture or mounting a large TV. So next time you’re deciding between the two, choose the right tool for the job to keep your walls safe and your items secure.
