Hello Rich_Art,

It was an easy way to determine thread pitch. By using this method you have an easy way to get the pitch right on and will use that to determine the other parts of the geometry. You don't have to spend your time figuring out or inputting to many values, you just need to know how many threads per inch / mm you want to model. Hope that makes sense, I'm not so good at explaining things.

Ah ok.. Thanks for the clarification...

Peace,
Rich_Art. ;-)

Hello Rich_Art,

By the way if you are using metric sizes the pitch is easy to determine since the second number should be the pitch. If this is the case you don't need to go through that first process, just use that number to start your pitch triangle.

Thank for the tip... :-) I hope I'll remember it when I'm making a new screw or bold.

Peace,
Rich_Art. ;-)
