How Wall Plugs Work

Each type of wall plug operates in a unique way to provide stability and secure fastening. Understanding how they work is crucial for choosing the right one for your project.

Expanding Eyelets

When inserted into a drilled hole, the plastic or metal arm of the expanding eyelet opens up inside the hole, creating a stable base for the screw. The screw is then tightened, compressing the arm and ensuring a secure hold.

Masonry Anchors

Masonry anchors are designed to work with masonry material. When the screw is tightened, the pointed tip of the metal sleeve expands and grips the surrounding material, creating a strong hold.

Hollow Wall Anchors

Hollow wall anchors work by expanding a plastic or metal sleeve as the screw is tightened. The expansion creates a secure base within the hole, providing a stable fastening point.

Plastic Expansion Anchors

Plastic expansion anchors function by inserting a plastic or metal sleeve into a drilled hole. As the screw is tightened, the sleeve expands, creating a secure base for the screw.
