Concrete Wall Plugs

Anchors or wall plugs are used to fasten elements and construction materials to concrete surfaces.

Wall plugs are optimally suited for repair work and household needs where high load-bearing capacity is not required. The design and purpose of concrete wall plugs can vary.

Features and types

Concrete wall plugs are also applicable in other materials — natural and artificial stone. Main types:

• Plastic models have a single expansion section — unlike wall plugs for brick. Concrete has high strength throughout its volume, so there is no need to search for a solid base.
• Metal nail-in anchors of the expansion type withstand higher loads. After the nail is driven in, the rear part of the sleeve expands and is held firmly in place.

Other wall plugs are also used for concrete, including flange-type models. The choice depends on the type of material, equipment, or furniture being attached and its characteristics, including weight.

Before installation, the hole is marked and drilled, then fully cleaned of dust and debris. To improve fastening quality, the prepared hole is filled with an adhesive compound made from dry adhesive.
