Molly bolts are a type of wall anchor that can be used to hang items of moderate weight on walls. They are considered more durable and reliable than traditional drywall anchors. They are also sturdier than other anchors as the anchor expands at the back once lodged in the wall, allowing for a firmer hold. They can be made of plastic or metal, with plastic molly bolts being more difficult to use and preferred by professionals. To install a large plastic drywall molly, you will need to pre-drill a hole, insert the molly bolt, and then use a screwdriver to drive the screw securely into the anchor.
| Characteristics | Values |
|---|---|
| Installation | Drill a hole in the wall, insert the anchor, and tap it in with a hammer or mallet. Then, insert the screw into the anchor and tighten with a screwdriver. |
| Removal | Use a steel drill bit larger than the anchor's shank to drill into the screw hole. Push the remaining shank into the cavity, then repair the original hole. |
| Use case | Suitable for hanging medium-weight items such as curtain rods, picture frames, and mirrors. |
| Weight limit | Can hold up to 50 lbs, with some variations holding up to 75 lbs per pair. |
| Materials | Can be made of plastic or metal. |
| Advantages | Sturdier than other anchors due to expansion at the back, providing a firmer hold. |
| Disadvantages | Prone to spinning during installation, especially on hard or repaired surfaces. Not as easy to remove as plastic anchors. |

What You'll Learn
Drilling a pilot hole
Firstly, clear the workspace and ensure you have all the necessary tools and safety equipment. Mark the location where you plan to install the drywall molly with a visible marker or chalk. This will ensure that you drill in the correct spot. Choose a drill bit that corresponds to the width specified by the manufacturer of your drywall molly. Using an incorrectly sized drill bit can cause the anchor and screw to fall out, compromising the stability of your project.
Next, carefully drill the pilot hole at your marked location. Take your time and maintain a steady hand to ensure the hole is straight and clean. Once the hole is drilled, inspect it to ensure it aligns with the manufacturer's specifications for depth and width. It is crucial that the hole is drilled to the correct dimensions to ensure a secure fit for your drywall molly.
After drilling the pilot hole, use a small block of wood and a hammer to gently tap the anchor into the hole. This will ensure that the anchor is flush with the wall and securely lodged in place. You can now proceed with the remaining steps of installing your large plastic drywall molly, following the manufacturer's instructions for a safe and successful installation.
Drilling a precise pilot hole is essential for the overall stability and security of your project. Taking the time to measure and drill accurately will ensure that your large plastic drywall molly can withstand the desired weight and provide a firm hold for your installation. Remember to always refer to the manufacturer's instructions and take the necessary safety precautions when operating power tools like drills.

Inserting the molly bolt
Now you're ready to drill. Put on safety goggles and a dust mask, then drill a pilot hole at the centre point you marked. Drill slowly and carefully, to a depth of around 1/2 inch, so you don't hit any electrical wires or plumbing. The hole should be slightly smaller than the width of your molly bolt.
Next, insert the pointed tip of the bolt into the hole and gently tap it with a hammer or screwdriver until it's flush with the wall. Finally, insert the screw into the hollow middle of the bolt and turn it clockwise with a screwdriver. Don't overtighten, as this could damage the drywall.

Tapping the bolt
It is important to note that the tapping should be done gently but firmly, to ensure that the molly bolt is securely in place without damaging the wall. The small block of wood is used to distribute the force of the hammer more evenly and to protect the molly bolt from direct impact.
When tapping the bolt, make sure that it is level and straight. This will help ensure that the molly bolt is inserted correctly and reduces the risk of it becoming crooked or misaligned during installation.
The tapping process should continue until the molly bolt is firmly in place and flush with the wall. Once this is achieved, you can move on to the next step, which is tightening the screw to expand the anchor in the wall.
Overall, tapping the bolt is a crucial step in installing a plastic drywall molly. It ensures that the molly bolt is securely lodged in the wall and ready to bear weight. By following the manufacturer's instructions and taking care during this step, you can ensure a safe and sturdy installation.

Tightening the screw
When tightening the screw of a large plastic drywall molly, it is important to follow these steps carefully to ensure a secure and stable anchor:
Prepare the Workspace
Clear the area where you will be working to ensure you have enough room to move around and handle the tools and objects safely. Gather all the necessary tools and materials, including a drill, screwdriver, and the object you plan to hang.
Drill a Pilot Hole
Before inserting the molly bolt, you need to drill a pilot hole in the desired location. Use a drill bit that is slightly smaller than the width of the molly bolt. Slowly drill to a depth of about ½ inches to avoid hitting any electrical wires or plumbing in the wall. It is important to wear safety goggles and a dust mask to protect yourself from debris and dust during this step.
Insert the Molly Bolt
Choose an appropriate-sized molly bolt that can accommodate the weight of the object you will be hanging. Insert the pointed tip of the molly bolt into the pilot hole and use a hammer or the end of a screwdriver to gently tap it into the wall until it is flush with the surface. The molly bolt should have sharp tips or metal "teeth" that grip the drywall securely.
Now, you can tighten the screw. Insert the screw into the hollow middle of the molly bolt and turn it clockwise using a screwdriver. Do not overtighten the screw, as this can damage the drywall. As you tighten the screw, the molly bolt will expand in the wall, providing a firmer hold. The screw threads added by the molly bolt will allow you to install and remove objects multiple times without losing strength.
Hang the Object
Once the molly bolt and screw are securely in place, you can hang your desired object. Ensure that the weight of the object does not exceed the capacity of the molly bolt to prevent any damage to the wall.

Hanging your object
Now that you have inserted your large plastic drywall molly, you can hang your desired object. Make sure it is not too heavy for the bolt, or it may rip the plaster and crash down. Molly bolts can typically hold up to 50 pounds, with some capable of holding up to 75 pounds. They are ideal for mounting medium-weight fixtures such as curtain rods, large picture frames, and mirrors.
If you are hanging something heavier, consider using a pair of molly bolts, as they can hold up to 150 pounds together. You can also use other types of bolts, such as toggle bolts, which can hold up to 50 pounds per pair, or expansion anchors, which can hold up to 100 pounds per pair.
When hanging your object, place it or any supplemental hanging hardware between the screw and the fastener, then tighten it until secure. If you need to remove the screw once installed, it is best to replace the wall anchor as well.
To remove a hollow wall anchor, hammer it into the wall and fill the hole it leaves with drywall compound. To remove a molly bolt, you can try to remove the head from the bolt. Sometimes, you can twist the top off by inserting one point of a small needle-nose plier into the bolt hole and grasping the outside edge of the top with the other side.
If you are hanging a very large, heavy picture or mirror, you may want to consider using no-stud picture hangers. These are hooks specifically designed for hanging mirrors or heavy artwork and can support up to 200 pounds each.
