This SAE Standard covers the dimensional and general specifications, including performance requirements, for carbon steel self-drilling tapping screws suitable for use in general applications having point Styles 2, 3, 4, and 5. It is the objective of this document to ensure that carbon steel self-drilling tapping screws, by meeting the mechanical and performance requirements specified, shall drill a hole and form or cut mating threads in materials into which they are driven without deforming their own thread and without breaking during assembly. SAE J78 is being revised to update some of the testing procedures and add requirements for point Styles 2, 3, 4, and 5, which are in common use.
