Concrete fasteners are primarily held in place through friction. When these fasteners, such as anchors or screws, are installed into concrete, they create a tight fit as they are driven into the material. The surfaces of the fastener and the concrete come into close contact, generating friction that helps to resist pull-out forces. The effectiveness of this friction depends on the quality of the fit and the compressive strength of the concrete itself.

In contrast, adhesive bonding relies on glue or similar substances to adhere materials together, which is not the primary mechanism for concrete fasteners. Mechanical locking might refer to designs where a component interlocks physically with another, but this is not the main principle at work for standard concrete fasteners. Weight distribution involves the spread of weight across surfaces, which may contribute to the overall load management but does not describe how fasteners are secured to concrete.
