What is a Self-Drilling Screw?

Working on the same principle as drill bits and cutting tools, self-drilling screws allow you to drill into materials such as wood or steel with pre-drilling holes. The flute at the end of the screw allows it to bite into the materials to secure them together. We offer both off-the-shelf and specially made stainless steel self-drilling screws.
