I quickly calculate proper tap-drill diameters using this simple formula. Tap-drill diameter equals nominal diameter minus thread pitch. For example, drill size for a 3/8-16 thread is 0.375 0.0625 ...
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 ...
