3. Applications:


As their name implies, self-drilling screws operate on the same principles as drill bits and other cutting tools. For any cutting tool, performance is governed by cutting speed, feed rate, depth of cut and the work material itself. Then, installation performance of selfdrilling screws can be linked to the basic cutting tool parameters where suggested optimal parameter values are listed by nominal screw size in the table.


When selecting a self-drilling screw, consider the material thicknesses and types of materials to be joined. Following are some key design features to look for when selecting suitable fasteners.
