self drilling screw for wood

The designation 1% 4% 2014 typically reflects specific characteristics associated with the screw's design and material composition, indicating its strength and suitability for particular applications. In many cases, the numbers denote the alloying elements in the screw's material, particularly in the context of steel to enhance corrosion resistance and overall durability. For instance, 1% might refer to the percentage of a certain alloy, while 4% could represent a different additive, both contributing to the screw's ability to withstand environmental stresses.

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.
