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.

For effective penetration, make sure that at least three threads of the fastener are inside the material.
