Revisiting Threads

Image
Can you imagine a world without threaded  nuts and bolts? When you think about it, almost everything in the world is held together by nuts and bolts - vehicles, homes, bridges, chairs just to name a few. You could say that our lives are literally hanging by a thread.  Of course, threads are used in other materials as well such as pipes. And threads come in different pitches; some are standard and some are metric; some are internal and some are external. And it's a machinist's job to make sure these threads are precise for the jobs they must perform. So, as a veteran machinist with over 40 years of experience, I have posted a few thread tips and created some GrafnCalc83 programs to help you double check your calculations for external pipe threads , internal pipe threads , and for diameter calculation  over three-wires of 60 degree threads.
