Plastic screw inserts, also known as drywall anchors, are used to attach items to walls when wall studs are unavailable. They can be installed using a power drill or a manual screwdriver. When using a drill, select a drill bit that is slightly smaller than the shaft of the screw insert and drill a hole in the wall. Push the insert into the hole and use a screwdriver to twist in the screw. If you don't have a drill, you can create a pilot hole with a nail and a hammer or even a screwdriver. This method may not be as precise, but it will get the job done.

What You'll Learn
Choosing the right plastic screw insert
When choosing the right plastic screw insert, there are several factors to consider, including the type of wall, weight of the object, type of insert, and the type of screw.
Firstly, the type of wall you are working with will determine the type of plastic screw insert you need. There are three main types of walls: plaster wall, drywall, and masonry. If you are working with drywall, it is crucial to be cautious and not drill too deeply, as this can lead to wall damage.
Secondly, consider the weight of the object you plan to hang. Plastic wall inserts, also known as expansion anchors, are typically used for hanging objects that weigh less than 30 pounds. For heavier items, you may need to opt for a different type of anchor or consider using multiple mounts for added support and stability.
Thirdly, the type of insert is an important consideration. Press-fit inserts, for example, are widely used in electronic enclosures and automotive components. They provide secure attachment points for screws and ensure the integrity and durability of the connection. Helical inserts, also known as coil inserts, are made from materials like stainless steel or brass and are used to reinforce or repair threaded holes in plastic components. Ultrasonic-assisted threaded inserts are another option, particularly useful in automated applications, but they require careful handling to avoid damaging the material.
Lastly, selecting the right screw for the insert is crucial. Ensure that the screw size matches the specifications of the insert and the requirements of your application. Consider factors such as the diameter, length, and thread specifications of the screw. It is also important to use the right tools for installation, such as an electric drill for concrete or wood walls and a drill or awl for drywall.

Tools needed for installation
The tools you will need to install plastic screw inserts will depend on the type of wall you are working with and the type of insert you are using.
If you are working with drywall, you will need a flathead or Phillips screwdriver, a drill, driver bits, a set of drill bits, and a hammer. You can use the drill to create a pilot hole for the insert, and then use the screwdriver to insert the screw. If the plastic sleeve anchor is tight, gently tap it with a hammer until it is flush with the drywall.
If you do not have a drill, you can use a screwdriver to create an indentation in the wall where you want the middle of the anchor to go. Make sure the hole is small enough so that the anchor has something to grip as it goes in. You can then use the screwdriver to insert the screw into the anchor.
For brick or exterior block walls, you will need a stud finder to ensure there isn't a stud behind the wall. You can then use a pilot bit to make a hole in the wall, insert the tip of the anchor, and use a screwdriver to get the anchor flush with the wall.
Needle-nose pliers can be useful for removing plastic screw inserts.

Preparing the wall
Firstly, identify the type of wall you are working with. Is it drywall, concrete, or another material? This will determine the appropriate tools and techniques for installation. For instance, if you are working with drywall, also known as gypsum board or wallboard, it is important to note that drywall anchors are typically used when wall studs are unavailable.
Next, mark the desired location on the wall where you plan to insert the plastic screw insert. This step is crucial as it ensures accurate placement. Use a pencil or a marker to indicate the exact spot. If you are working with drywall, you can create a small starter hole by tapping a nail into the drywall's paper covering. This step is specific to nylon (plastic) anchors; metal anchors are strong enough to create a hole on their own.
Now, it's time to gather the necessary tools and hardware. For installing plastic screw inserts, you will typically need a drill, drill bits, a screwdriver (either flathead or Phillips), and, of course, the plastic inserts and screws. It is important to consult the instructions provided with your specific plastic screw inserts to ensure you have the correct size of drill bit. If the instructions are unavailable, you can estimate the bit size by visually comparing the bits to the shaft of the sleeves. Remember, it is always better to start with a smaller bit and enlarge the hole if needed.
Once you have marked the location and gathered your tools, it's time to drill the hole. Fit the selected drill bit into your drill and carefully drill into the marked location on the wall. Ensure the drill bit is firmly secured in the drill before starting. Drill to a depth that matches the length of the plastic insert and screw. If you are working with drywall, you may need to gently tap the plastic sleeve into the hole with a hammer until it is flush with the drywall.
Finally, before inserting the plastic screw insert, it is important to clean and prepare the hole. Use a small brush or compressed air to remove any debris or dust from the drilled hole. This step ensures that the plastic insert will sit securely and flush with the wall.

Inserting the plastic screw insert
Preparing the Surface:
Start by gathering the necessary tools, including a drill, screwdriver, and hammer. While a power drill is not necessary, it can make the process easier. Consult the instructions on the plastic insert package to select the appropriate drill bit size. If no instructions are provided, estimate the bit size by comparing it to the shaft of the insert. It's generally recommended to err on the side of a smaller bit size to avoid making an oversized hole.
Creating the Pilot Hole:
Use the drill bit to create a pilot hole in the desired location. The hole should be slightly smaller than the insert to ensure a tight fit. If you don't have a drill, you can use a screwdriver to create a deep indentation where the insert will go. Alternatively, you can use a nail and a hammer to create the pilot hole, starting with a few gentle taps.
With the pilot hole ready, insert the tip of the plastic screw insert into the hole. Gently tap the insert with a hammer if needed until it is flush with the surface. Ensure that the insert is secure and tight against the back of the surface material. If it resists or feels tight, do not force it. Instead, remove the insert, drill a slightly larger hole, and then insert a new one.
Securing with a Screw:
Once the insert is in place, carefully screw in the provided screw. Be careful not to over-tighten the screw, as this can cause the insert to spin in place and become useless. When done correctly, you should hear a clicking sound, indicating that the plastic anchor has split in two to grip the back of the surface securely.
Plastic screw inserts provide a sturdy and secure hold, making them ideal for various applications, from hanging shelves to mounting heavy objects on walls. Remember always to follow the instructions provided with your specific plastic screw inserts for the best results.

Securing the screw
If you are not using a power drill, you can use a screwdriver to manually twist the screw into the insert. Ensure that you do not over-tighten the screw, as this can cause the anchor to spin in place, rendering it useless. This is because over-tightening can cause the anchor to become loose within the wall, resulting in a larger hole than intended.
When using a power drill, be cautious not to apply too much force, as this can also lead to over-tightening. It is recommended to drill at a low speed to maintain control and avoid potential damage to the screw, insert, or wall.
Additionally, be mindful of the weight restrictions of the plastic inserts. Drywall anchors, for example, typically support around 50 pounds of weight each. For heavier items, consider using stronger alternatives such as winged plastic anchors or snap toggle bolts. These options provide increased strength and stability, making them suitable for hanging heavier objects.
If you are working with heavy items, it is recommended to attach them directly to wall studs whenever possible, instead of relying solely on plastic screw inserts and drywall anchors.
