What is used to secure items to a concrete surface?

Concrete anchors are specifically designed to secure items to a concrete surface effectively. They provide a robust method of fastening due to the unique properties of concrete, which requires special consideration for attachment. Concrete anchors come in various types, including wedge anchors, sleeve anchors, and drop-in anchors, each suiting different applications and load requirements.

Using anchors ensures that the secured items remain stable and can withstand various stresses, such as tension and shear forces, which are essential in construction and electrical installations. This capability makes concrete anchors the most appropriate choice for attaching fixtures, equipment, or other items directly to concrete surfaces.

In contrast, adhesives may not provide sufficient strength for heavy items or may fail over time due to environmental factors. Expansion bolts, while they can serve a similar purpose, are a type of concrete anchor and would fall under that category. Wood screws are not suitable for concrete applications due to their design and material, which are better suited for attachment to wooden surfaces.
