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 key advantages of self-drilling screws for heavy steel is their ability to save time and labor costs. Traditional screws require pre-drilling a hole before fastening, which can be time-consuming, especially when working with heavy steel materials. Self-drilling screws eliminate the need for this extra step, allowing for quick and efficient installation. This is particularly important in industrial settings where production timelines are tight and every minute counts.
