Magic By The Self-tapping Screws

Self-tapping screws are known to drill holes in materials and devices. These are good but do you know that they can be used to join two dissimilar materials? Yes, do not worry if you have to bring together two different materials. Self-tapping screws have the ability to read the qualities of the materials and based on the requirement, make holes in them. They first create threads before making holes allowing the screw to fit into the material tightly.
