Drywall anchors are used to hang items on drywall surfaces. They are necessary when there are no wall studs available to support the weight of the item being hung. The type of anchor used depends on the weight of the item being installed. Plastic expansion anchors, for example, are best used for hanging lightweight items, while steel hollow wall anchors are meant for heavier objects. To install a drywall anchor, you must first drill a pilot hole in the wall. Then, place the anchor in the hole and tap it into the wall. Finally, use a screwdriver to drive the screw into the anchor.

What You'll Learn
Mark the spot with a pencil and drill a pilot hole
Marking the spot where you want the anchor to go is the first step in installing drywall screws with plastic anchors. Use a pencil to mark the spot. This will ensure that you drill in the correct place.
Once you have marked the spot, you will need to drill a pilot hole. Fit your drill with a bit that matches the diameter of the anchor you are installing. You should opt for a drill bit that is slightly smaller than the width of the anchor. Check the drywall anchor package for the correct bit size. Hold the drill at a 90-degree angle relative to the wall and keep it steady as you drill. Take your time drilling to make sure the job is done right. If you are drilling into a wall, be aware that there may be plumbing or wiring behind it.
If you are using a plastic expansion anchor, you can simply push it into the pilot hole by hand. For a toggle bolt, guide the wings through the hole and listen for them to pop open, then screw the anchor head firmly into place. For a strap-type toggle anchor, insert the toggle through the pilot hole and pull the straps towards you to set the toggle against the back of the wall. Then, slide the anchor collar along the straps and against the wall surface. Once the collar is against the wall surface, snap off and discard the plastic straps.
If you are installing a hollow wall anchor or molly bolt, you will need to tap the anchor into the pilot hole with a hammer. Make sure that the collar of the anchor is flush with the wall surface. Do not drive the collar beneath the surface of the wall. For some types of anchors, you may need to fold down the flanges to install the anchor.

Tap the plastic anchor into the hole with a hammer
When installing a plastic drywall anchor, you'll first need to drill a pilot hole into the drywall. The hole should be slightly smaller than the anchor. Once you have your pilot hole in place, you can insert the anchor.
If you're using a plastic expansion anchor, simply push it into the pilot hole by hand. For other types of plastic drywall anchors, you may need to use a hammer to tap the anchor into the hole. This technique is suitable for unthreaded drywall anchors, as attempting to hammer in a threaded anchor will damage the anchor and the wall.
To tap the plastic anchor into the hole with a hammer, first place the anchor into the pilot hole. Use a hammer to carefully tap the anchor into the hole until the collar of the anchor is flush with the wall surface. Don't drive the collar beneath the surface of the wall. The anchor should go into the hole with light taps and fit snugly. You may need to tap the anchor with a hammer to drive it completely into the hole. Make sure you use light taps and don't force the anchor into a hole that's too small, as this could damage the anchor or the drywall.

Insert the screw into the anchor
When inserting the screw into the anchor, it's important to be careful and deliberate in your actions to avoid damaging the anchor, screw, or wall. Firstly, identify the type of anchor you're working with. For example, if you're using a plastic expansion anchor, it will have a conical shape and raised rings or barbs along its body to improve grip.
For a plastic anchor, you'll need to create a small starter hole by tapping a nail into the drywall's paper. Place a Phillips or flat-head screwdriver into the notched head of the anchor and turn it clockwise. Apply firm, but not hard, pressure to draw the anchor into the drywall. It's important not to twist too hard, or you may strip the head of the anchor.
Once the anchor is flush with the drywall, you can insert the screw. You can use a drill for this step, but proceed slowly and carefully to avoid overdriving the screw. As you drive the screw into the anchor, the shank of the anchor will split and expand into flanges or wings, gripping the interior of the drywall. This action helps to secure the anchor and prevents it from easily pulling out.
If you're using a screw-style toggle bolt, you'll need to remove the spring-loaded toggle from the screw before inserting it. This type of anchor typically requires a larger pilot hole. For a strap-type toggle anchor, insert the toggle through the pilot hole, then pull the straps towards you to set the toggle against the back of the wall. Finally, snap off and discard the plastic straps.

Use a screwdriver to tighten the screw
When installing drywall screws with plastic, it's important to use the correct tools and techniques to ensure a secure and long-lasting hold. Here's a detailed guide on using a screwdriver to tighten the screw:
Prepare the Drywall
Begin by marking the spot where you want the screw to go with a pencil. This will guide your drilling and ensure accurate placement. If you're using a plastic expansion anchor, you'll need to create a pilot hole. Drill the hole at a 90-degree angle relative to the wall, ensuring it's the appropriate size for your anchor.
Insert the Anchor
With the pilot hole ready, it's time to insert the plastic anchor. Gently tap it into the hole with a hammer until it sits flush with the wall surface. Ensure it fits snugly and doesn't spin freely, as this can cause issues with tightening the screw.
Tightening the Screw
Now, you can proceed to tighten the screw using a screwdriver. Place the screwdriver into the notched head of the screw. Apply moderate but firm pressure as you turn the screwdriver in a clockwise direction. This will drive the screw into the anchor and tighten it securely. Be careful not to over-tighten, as this can strip the surrounding drywall or damage the anchor.
Addressing Loose Screws
If you encounter a loose screw in your drywall anchor, there are a few solutions. One method involves removing the screw, inserting wooden toothpicks into the anchor to create grip, and then reinserting and tightening the screw. Alternatively, you can use expandable glue to secure the anchor in place before re-tightening the screw.
Remember to select the appropriate type of anchor and screw for your specific application. For heavy items, consider using threaded anchors or seeking support from wall studs to ensure a sturdy and reliable hold.

Winged plastic anchors prevent the anchor from pulling out
When installing drywall screws with plastic, it is important to consider the type of anchor you are using. Winged plastic anchors, also known as butterfly anchors, are specifically designed for use in drywall applications. They are inserted into a pilot hole and tapped gently with a hammer until flush with the wall. As a screw is driven into the anchor, the anchor expands and the wings open up behind the wall, providing extra grip and preventing the anchor from pulling out.
To install winged plastic anchors, start by marking the spot where you want the anchor to go with a pencil. Drill a pilot hole at a 90-degree angle, ensuring the hole is slightly smaller than the collar of the anchor. Gently tap the anchor into the hole with a hammer until it is flush with the wall. Finally, drive the screw into the anchor, being careful not to overtighten as this can damage the drywall.
Winged plastic anchors are suitable for various materials, including drywall, concrete, and brick. They are commonly used for hanging fixtures like shelves, mirrors, pictures, and light fixtures. The weight capacity of winged plastic anchors may vary depending on size and quality, so it is important to check the manufacturer's recommendations.
By following these steps and choosing the appropriate winged plastic anchors, you can securely fasten objects to walls or other surfaces without the risk of them falling or pulling out.

Frequently asked questions
First, mark the spot where you want the anchor to go with a pencil. Drill a pilot hole at a 90-degree angle, then insert the plastic anchor by hand, tapping it lightly with a hammer until it's snug. Finally, use a screwdriver to screw in the screw.
No, not every type of wall anchor requires a pre-drilled pilot hole. However, it is often a helpful first step and can save time. Metal anchors, for example, do not need a pilot hole as they are strong enough to create a hole on their own.
Drywall anchors are used to attach items to walls when wall studs are unavailable. They are designed to add strength to hollow drywall and help hold your fastener in place.
