Advanced machine tool and cutting tool technologies reduce the cost and boost the quality of producing internal threads in aerospace materials. The diameter of a thread milling cutter is smaller than ...

The strength of some internal threads is more sensitive to tap diameter than previously thought. • Cold-formed threads are no stronger than cut threads when holes are correctly sized. • Cut threads ...

Most engineers who deal with bolted joints are familiar with torque tables for SAE-grade bolts, but these are all too often used without regard for the yield strength of internal threads or the bolt’s ...
