3mm Screw

Need help? We are here.

I’m looking for a way to design a 3mm screw with a .5 pitch.

Does anyone have that design to share, or can someone instruct me as to how to achieve this precise design?

I can make a screw, but don’t understand how to be precise with the pitch and thread depth.

Hi,

you should have a look at ISO metric screw thread - Wikipedia to get the precise dimensions and exact shape to sketch.
