SAE J 78-2013 (SAE J78-2013)
Steel Self-Drilling Tapping Screws
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.
It is the objective of this standard to insure 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.
Appendix A is included to provide a recommended technique for measuring the case depth on the screws.
