Plastic wall plugs, also known as drywall anchors or expansion anchors, are used to reinforce screws in wall surfaces. They are typically used when there is no stud in the desired location, or when hanging items on drywall. The process of installing a plastic wall plug involves marking the desired location with a pencil, drilling a pilot hole, inserting the wall plug, and then driving in the screw. The screw causes the back of the wall plug to expand, creating a strong connection between the screw and the wall. This guide will take you through the steps to successfully install a plastic wall plug.

What You'll Learn

Mark the spot where you want the anchor to go
Marking the spot where you want the anchor to go is the first step in installing plastic wall plugs. This process is also known as drywall anchoring. It is a useful method when you need to hang something on a wall and there is no stud in the right spot.
To begin, select a desirable spot to hang your item. You should choose a section of the wall where your item won’t be forced to compete for space with other fixtures and decorations. Once you have decided on the location, mark it with a pencil. This will indicate the intended location of the plastic anchor.
It is important to note that plastic wall anchors are typically used for hanging lightweight pictures and small decorative objects. The weight of the object should be kept under 30 lbs. to prevent the anchor from pulling out of the wall. If you are hanging a heavier item, such as a TV, it is recommended to screw into at least one wall stud.

Drill a pilot hole
To install plastic wall plugs, you'll need to start by drilling a pilot hole. Mark the spot where you want the anchor to go with a pencil. This will be your pilot hole.
Choose a drill bit that is slightly narrower than the anchor. The diameter of the drill bit should be about the same as that of the anchor you are installing. Hold the drill at a 90-degree angle to the wall and keep it steady as you drill. Drill straight into the wall and ensure that the hole is as straight as possible.
If you don't have an electric drill, you can use an awl, a hammer and nail set, or even a Phillips-head screwdriver to make the pilot hole. If you use a screwdriver, press the tip against the wall and twist it back and forth to create the hole.
Once you have your pilot hole, you can use it to install any type of plastic wall anchor.

Push the anchor into the pilot hole
When you need to hang something on a wall and there's no stud in the right spot, plastic wall anchors, also called expansion anchors, are a great solution. They reinforce a screw in the wall surface so it can't be easily ripped out. Wall anchors can be used in drywall, concrete, brick, metal or wood.
To install a plastic wall anchor, start by marking the intended location of the anchor with a pencil. Then, drill a hole in the wall for the anchor. The hole should be drilled at a precise 90-degree angle, and its diameter should be slightly narrower than that of the anchor.
Now, you can push the anchor into the pilot hole. Use your finger to push the plastic wall anchor into the hole as far as it will go. You may need to tap it gently with a hammer to get it to fit snugly inside the hole, but be careful not to force it if the hole seems too small. If the anchor bends, remove it with a pair of pliers and insert a new one. The anchor should be flush with the wall surface.
Once the anchor is in place, you can place a screw in its centre. If you bought a package that includes screws, use one of the screws provided. If you purchased the anchors separately, select an appropriately-sized screw.

Place a screw in the centre of the anchor
Once you have your pilot hole in place, it's time to place a screw in the centre of the anchor. If you purchased the anchors separately, you'll need to select the right screw for the anchor. If the screw size isn't listed on the package, you may need to try a few different screws before finding the perfect fit. The screw should fit snugly inside the anchor.
If you're using a plastic expansion anchor, simply push it into the pilot hole by hand. You can use your finger to push the anchor as far as it will go into the hole. Then, gently tap it with a hammer until the anchor is flush with the wall surface. A rubber mallet is best, but a small finish nailer or even a hammer will also work.
Now, place a screw in the centre of the anchor. You can use a screwdriver or an electric drill to screw in a self-drilling anchor. If you're using a manual screwdriver, apply moderate pressure to install the anchor. Be careful not to overtighten it, as this could damage the anchor or the wall.
If you're using a hollow wall anchor or molly bolt, tap the anchor into the hole with a hammer, then tighten the central screw with a screwdriver. For a toggle bolt, guide the wings through the hole and wait for them to pop open before screwing the anchor head firmly into place.

Tighten the screw
When you have inserted the plastic wall plug into the pilot hole, it is time to tighten the screw. Place the screw in the centre of the wall plug. If you purchased the plugs and screws together, the screws should be the correct size. If you bought the plugs separately, you may need to try a few screws to find the perfect fit.
Once you have the right screw, use a screwdriver to tighten it. You can also use a drill, but be careful to go slowly so that you do not overtighten the screw. As you turn the screw, the plastic wall plug will expand to grip the sides of the hole. This will reinforce the screw in the wall surface so that it cannot be easily ripped out.
If you are using a threaded drywall anchor, you only need to apply moderate pressure with a screwdriver to install it. The anchor's point will self-drill into the wall. Ensure that you keep applying pressure so that the anchor does not spin in the hole and dig out the drywall.
If you are using a hollow wall anchor or molly bolt, tighten the central screw with a screwdriver after tapping the anchor into the hole with a hammer. For a toggle bolt, you need to guide the wings through the hole and listen for them to pop open. Then, screw the anchor head firmly into place.

First, mark the intended location of the plastic wall plug with a pencil. Drill a pilot hole in the wall for the anchor. Then, push the plastic wall plug into the hole with your finger until it is flush with the wall. Finally, place a screw in the centre of the wall plug and tighten with a screwdriver.
You will need a drill to create the pilot hole, and a screwdriver to tighten the screw. You may also want a hammer to tap the plug into the hole, and a stud finder to locate a wall stud if you are hanging something heavy.
Plastic wall plugs can be used in drywall, concrete, brick, metal or wood.
