The M12 in the term refers to the metric screw thread size, which measures 12 millimeters in diameter. This size is commonly used for medium to heavy-duty applications where robust anchoring is crucial. Chemical anchors, unlike mechanical anchors, rely on a chemical adhesive to create a strong bond between the anchor and the substrate. They offer advantages like high load-bearing capacity, resistance to dynamic loads, and minimal impact on the surrounding material.

One of the primary benefits of using 2-inch self-drilling screws is the time savings they offer. In projects where speed is essential, these screws can significantly reduce the overall construction time. Without the need to pre-drill holes, workers can quickly set up and fasten materials together, increasing productivity. This is particularly advantageous in situations where time constraints are a critical factor, such as in commercial construction or during emergency repairs.
