Hex head self-drilling screws from LITUO Fasteners are engineered to be corrosion resistant and come in various sizes and materials.
Depending on the size, the applications of the hex self-drilling screws can vary – the smaller screws are used in applications like fixing thin gauge metals and fixing metal to wood. The larger screws are used in roofing and other industries which require self-drilling through tough metals. Our screws come in stainless steel, alloy steel, carbon steel, and other materials that prevent corrosion. If the hex head self-drilling screws are used in extremely hard materials, it is advised to use them after a pilot hole has been drilled.
Our screws are case hardened and heat-treated for applications requiring fastening of soft materials on hard ones. With a lower installation torque, the threads on these screws allow for a quick transition from drilling to tapping. For effective penetration, make sure that at least three threads of the fastener are inside the material.
