J78_201304 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 document 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.
