Machinist Kalc Programs

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.

A hexagon, as mentioned in a previous post , is often used in nature due to its amazing strength. One of the earliest hexagonal written thoughts dates back to 36 BC when Roman polymath, Marcus Terentius Varro, reported that the hexagonal shape makes the most efficient use of space and building material. (Source: Wikipedia ) From that point, builders and manufacturers have been busy as bees using the hexagon to build their man made creations.  Image courtesy of   Meggyn Pomerleau With that being said, a machinist often uses two of history's genius hexagon inventions - hex nuts and bolts with hex heads. These handy fasteners allow for an excellent grip without slippage when tightening. As machinists, we also make plenty of hexagons in our career. That's why I decided to revisit my hexagon tips  and GrafNCalc83 programs I created to calculate a  hex angle , hex point 1 , hex point 2 , and  diameter calculation for hex and square. My coworkers and I use these programs on a near-d
