Choosing the Right Hardware
Anchors for Different Loads
The weight of the item you’re hanging will determine the type of anchor you need.
| Weight | Anchor Type |
|---|---|
| Less than 25 pounds | Plastic anchors, toggle bolts, or small molly bolts |
| 25-100 pounds | Medium-sized molly bolts, hollow-wall anchors, or concrete screws |
| 100-200 pounds | Large molly bolts, expansion anchors, or cement anchors |
| Over 200 pounds | Heavy-duty concrete screws, chemical anchors, or wedge anchors |
Types of Anchors
* Plastic anchors: These are the most common type of anchor and are suitable for light loads. They are easy to install and inexpensive.
* Toggle bolts: These anchors have a foldable wing that spreads out behind the wall when the bolt is tightened. They are suitable for slightly heavier loads than plastic anchors.
* Molly bolts: These anchors have a spring-loaded sleeve that expands behind the wall when the bolt is tightened. They are suitable for medium to heavy loads.
* Hollow-wall anchors: These anchors are designed for walls with hollow spaces behind them, such as drywall or plasterboard. They have prongs that fold out and grip the inside of the wall.
* Concrete screws: These screws have a sharp point and aggressive threads that bite into the concrete. They are suitable for heavy loads.
* Expansion anchors: These anchors expand when they are tightened, providing a secure grip in the concrete. They are suitable for very heavy loads.
* Wedge anchors: These anchors are similar to expansion anchors, but they have a tapered shaft that wedges into the concrete when they are tightened. They are suitable for the heaviest loads.
Drilling the Pilot Holes
After marking the location of your holes, you’ll need to drill pilot holes to guide the anchors. For concrete walls, you’ll need a carbide-tipped drill bit rated for masonry.
When drilling the pilot holes, there are a few things to keep in mind:
Depth
The depth of the pilot hole will depend on the type of anchor you’re using. The general rule is to drill the hole as deep as the length of the anchor, plus the thickness of the object you’re hanging.
Diameter
The diameter of the pilot hole should be the same as the diameter of the anchor. The table below can help you determine the correct pilot hole size for the most common anchor types:
| Anchor Type | Pilot Hole Diameter |
|---|---|
| Concrete Nail Anchor | 1/8″ |
| Plastic Anchor | 3/16″ |
| Metal Anchor | 1/4″ |
Drilling Speed
When drilling into concrete, it’s important to use a slow drilling speed. This will help prevent the drill bit from overheating and chipping the concrete.
Dust Control
Drilling into concrete creates a lot of dust. It’s a good idea to wear a dust mask and safety glasses, and to use a vacuum cleaner to clean up the dust as you drill.
Installing Drywall Anchors
Installing drywall anchors is a common method for hanging things on concrete walls. These anchors expand when inserted into the wall, creating a secure hold for screws or nails. There are different types of drywall anchors available, so it’s important to choose the right one for the job.
Step 1: Choose the right anchor
The type of drywall anchor you choose will depend on the weight of the object you’re hanging and the thickness of the drywall. For light objects, such as picture frames or small shelves, you can use plastic anchors. For heavier objects, such as mirrors or cabinets, you’ll need to use metal anchors.
Step 2: Drill a hole
Once you’ve chosen an anchor, use a drill to make a hole in the drywall. The hole should be slightly smaller than the diameter of the anchor. Be sure not to drill too deep, as this can damage the drywall.
| Anchor Size | Drill Bit Size |
|---|---|
| 1/4″ | 3/16″ |
| 3/8″ | 1/4″ |
| 1/2″ | 3/8″ |
Step 3: Insert the anchor
Gently tap the anchor into the hole until it’s flush with the surface of the drywall. If you’re using a plastic anchor, you may need to use a hammer. Be careful not to overtighten the anchor, as this can also damage the drywall.
Once the anchor is in place, you can screw or nail the object into the anchor. Be sure to use screws or nails that are the correct length for the thickness of the drywall and the weight of the object.
Using Toggle Bolts
Toggle bolts are a type of anchor bolt that is specifically designed for use in concrete walls. They work by expanding behind the wall when tightened, creating a secure hold for the screw or bolt that is being used. Toggle bolts are available in a variety of sizes and lengths, so they can be used to hang a wide range of objects, from small pictures to heavy shelves.
To install a toggle bolt, first drill a hole in the concrete wall that is slightly larger than the diameter of the bolt. Then, insert the toggle bolt into the hole and tighten the nut until the toggle expands behind the wall. Finally, insert the screw or bolt into the toggle bolt and tighten it until the object is securely hung.
Toggle bolts are a relatively easy and inexpensive way to hang objects in concrete walls. However, it is important to note that they are not as strong as other types of anchor bolts, such as concrete screws or wedge anchors. Therefore, they should not be used for hanging heavy objects or in applications where the object will be subjected to a lot of force.
Types of Toggle Bolts
There are two main types of toggle bolts: spring-toggle bolts and mechanical-toggle bolts. Spring-toggle bolts are the most common type, and they are made with a spring-loaded toggle that expands behind the wall when tightened. Mechanical-toggle bolts are more durable than spring-toggle bolts, and they are made with a mechanical toggle that is tightened with a wrench.
Installation Instructions
To install a toggle bolt, follow these steps:
| Step | Description |
|---|---|
| 1 | Drill a hole in the concrete wall that is slightly larger than the diameter of the bolt. |
| 2 | Insert the toggle bolt into the hole. |
| 3 | Tighten the nut until the toggle expands behind the wall. |
| 4 | Insert the screw or bolt into the toggle bolt and tighten it until the object is securely hung. |
Hammering in Nails
Hammering nails into concrete walls is a more direct and familiar approach, but it requires more force and can cause damage if not done properly.
Materials you’ll need:
- Hammer
- Nails (masonry nails or concrete nails)
- Concrete drill bit (optional)
Steps to Hammering Nails into Concrete Walls:
- Mark the location: Mark where you want to hang the item using a pencil or chalk.
- Create a pilot hole (optional): While not necessary, using a concrete drill bit to create a small pilot hole can make hammering easier.
- Position the nail: Hold the nail perpendicular to the wall and align it with the pilot hole or marked location.
- Start hammering: Using a hammer, strike the nail firmly and steadily. Apply force evenly until the nail is about halfway into the concrete.
- Protect the wall: To prevent damage to the concrete, place a piece of wood or a nail protector on the wall around the nail as you continue hammering.
- Finish hammering: Continue hammering until the nail is fully embedded in the concrete, leaving a slight protrusion.
- Hang the item: Insert the hook or other hanging device into the nail head and hang your item.
| Nail Type | Description |
|---|---|
| Masonry Nails | Specifically designed for concrete walls, with hardened steel and a spiral shank for better grip. |
| Concrete Nails | Similar to masonry nails but with a slightly different shank design, also suitable for concrete walls. |
Hanging Heavy Objects
For heavier objects like shelves, mirrors, or artwork, you’ll need to use anchor bolts or toggle bolts to provide additional support. Here’s a step-by-step guide:
1. Determine the Weight of the Object
Calculate the total weight of the object and any additional weight it may carry (e.g., books for a shelf). This will help you choose the appropriate anchor.
2. Choose the Right Anchor
Select an anchor bolt or toggle bolt that can support the weight of the object and the type of concrete you have. For example, a 3/8-inch anchor bolt can hold up to 500 pounds in concrete.
3. Drill the Pilot Hole
Using a hammer drill, drill a pilot hole slightly smaller than the diameter of the anchor. The depth of the hole should be the length of the anchor plus 1/4 inch.
4. Insert the Anchor
Hammer the anchor into the hole until it is flush with the concrete surface. If using a toggle bolt, insert the bolt into the hole and spread the wings on the back to secure it.
5. Attach the Object
Use a bolt or screw to attach the object to the anchor. Tighten the bolt or screw until the object is securely fastened to the wall.
6. Test the Anchor
Before hanging the object permanently, test the anchor by pulling on it gently to ensure it is secure. If the anchor moves, remove the object and inspect the anchor for damage. If necessary, replace the anchor with a larger or stronger one.
| Anchor Type | Weight Capacity | Concrete Type |
|---|---|---|
| 3/8″ Anchor Bolt | 500 lbs | Normal-Weight Concrete |
| 1/2″ Toggle Bolt | 750 lbs | Lightweight Concrete |
| 3/4″ Wedge Anchor | 1,500 lbs | High-Strength Concrete |
Hiding the Hardware
When hanging heavy objects on concrete walls, it’s crucial to ensure the hardware stays concealed for a clean and polished look. Here are seven effective techniques to hide the hardware:
1. Use Toggle Bolts
Toggle bolts, also known as butterfly bolts or hollow wall anchors, expand behind the wall when tightened, distributing weight across a larger area. They’re ideal for hanging heavy items without drilling large holes.
2. Employ Sleeve Anchors
Sleeve anchors consist of a threaded sleeve that’s hammered into a drilled hole. The bolt is then inserted into the sleeve, which expands and locks it in place, concealing the hardware from view.
3. Utilize Tapcon Screws
Tapcon screws have a drill point at the tip, allowing them to be screwed directly into concrete without pre-drilling. Their self-tapping capabilities make them fast and convenient, while the countersunk head provides a flush finish.
4. Conceal with Wall Plugs
Wall plugs, also known as anchors or inserts, are soft plastic or rubber pieces that fit into drilled holes. They provide a secure hold and prevent the bolt from pulling out while remaining hidden behind the object.
5. Employ Decorative Bolts
Decorative bolts, such as carriage bolts with a domed head or hexagonal bolts, can add a stylish touch. They’re typically larger than standard bolts and can be customized to match the decor.
6. Use Wall Hooks
Wall hooks, especially those with multiple points of contact, can distribute weight effectively. They’re easy to install and concealable, making them suitable for lighter objects.
7. Apply Toggle Rods
Toggle rods, which consist of two rods connected by a spring, are threaded at both ends. They’re inserted through the wall and then tightened, applying pressure against the back of the wall to create a secure hold. The rods are concealed behind the object, leaving only the threaded end exposed for attaching hardware.
| Hardware Type | Description |
|---|---|
| Toggle Bolts | Expandable bolts that distribute weight across a larger area. |
| Sleeve Anchors | Expandable sleeves that lock bolts in place, concealing the hardware. |
| Tapcon Screws | Self-tapping screws that eliminate the need for pre-drilling. |
| Wall Plugs | Soft inserts that provide a secure hold and conceal the hardware. |
| Decorative Bolts | Stylish bolts that add a decorative touch and conceal the hardware. |
| Wall Hooks | Easy-to-install hooks that distribute weight and are concealable. |
