About plastic screw anchor

Types of plastic screw anchors

Plastic screw anchors come in different types, and each is suitable for specific applications. Understanding the various kinds of plastic screws for wall anchors allows users to choose the right type for their projects.

Expansion anchors

These anchors expand when a screw is inserted, providing a secure hold even in hollow spaces. They are ideal for drywall or hollow core doors.

Threaded anchors

Threaded plastic wall anchors resemble a screw but are made of plastic. They are designed to be screwed directly into drywall or other soft materials. Their threads provide a strong grip for hanging medium to heavy items, making them ideal for shelving, mirrors, or lighter furniture.

Capacity anchors

Cap anchors are designed to be inserted into pre-drilled holes in solid materials such as wood, masonry, or concrete. These anchors feature a concave cap shape that allows them to evenly distribute the load across a wider surface area. Hence, this minimizes the risk of the material cracking or breaking under pressure.

Expansion anchors

Expansion anchors are typically designed for use in masonry or concrete surfaces. They function by expanding outwards as a screw is tightened within the anchor. The expansion creates a secure and heavy load-carrying gripping. They are ideal for securing heavier objects such as shelves, furniture, or large tools in durable surfaces.

Screw-in plastic anchors (self-drilling anchors)

They are often used for drywall installations. These are designed with a sharp, pointed end that allows them to be easily screwed into the wall without the need for pre-drilling a hole. This makes them a popular choice for quick and easy installations.

All these materials provide flexibility, strength, and durability. These features help the anchors resist environmental conditions and lifting wear and tear.

  • Load capacity

    Typically, plastic screw anchors can support 5 to 30 pounds, depending on the anchor type and wall material. Heavier items should be installed using wall screws and anchors made of metal.

  • Corrosion resistance

    Plastic screw anchors are highly resistant to corrosion. This ensures long-lasting performance in humid or moisture-rich environments.

  • Easy installation

    Easy installation is one of the most notable features of plastic screw anchors. Users can install these anchors without specialized tools or equipment.

  • Versatility

    These anchors are often used with a wide range of wall materials, such as drywall, concrete, and plaster. Plastic screw anchors are particularly ideal for use in lightweight applications, such as hanging picture frames, mirrors, shelves, and curtains.

  • Flexibility

    The flexibility of plastic screw anchors allows them to compress slightly when a screw is tightened. This feature enables them to create a tight, secure fit within the hole, providing excellent gripping power. Their ability to withstand both torque and lateral forces further enhances their effectiveness in various applications.

How to install

  • Choose the right anchor

    Plastic screw anchors come in various shapes and sizes, each suited for specific wall types. These wall types include drywall, concrete, or brick. Selecting an anchor designed for the type of wall being used is important to ensure a secure hold.

  • Prepare the wall

    Clean the wall where the anchor will be installed. This prevents dust or debris from interfering with the installation process. Moreover, using a level or measuring tape to mark the position where the item will be hung ensures proper alignment.

  • Drill a pilot hole

    Drill a pilot hole slightly smaller than the anchor diameter. This allows the anchor to grip securely into the wall material. The pilot hole size will vary depending on the anchor size.

  • Insert the anchor

    Next, gently tap the plastic screw anchor into the pilot hole using a hammer or a rubber mallet. Ensure the anchor is flush with the wall surface. For self-drilling anchors, the anchor can be screwed directly into the wall without pre-drilling.

  • Attach the screw

    Finally, align the item with the anchor and insert a screw through the item into the anchor. Tighten the screw until secure, but be careful not overtighten. Overtightening can cause anchor or wall damage, compromising the hold.
