For fastening in concrete, it is important to know the strength of which component?

The strength of the anchor type is critical when fastening in concrete because anchors provide the necessary support and stability to the attached components. Different types of anchors, such as expansion anchors, wedge anchors, and adhesive (epoxy) anchors, have varying load capacities, installation methods, and performance characteristics based on concrete conditions. Knowing the strength of the anchor type ensures that it can safely hold the required load and withstand forces such as tension, shear, and vibration.

While the drive pin and epoxy are also important components in the fastening system, their specific values are contingent upon the anchor type used. Understanding the anchor type encompasses knowledge of how these components interact with the concrete and the load they must bear, making it the most comprehensive and vital factor in determining the overall strength of the fastening system.
