Does anyone know of a plugin for 3dsmax that will create accurate parametric screws? I am doing some parts re-manufacturing projects and it would be really useful to not have to manually model all of these.

I don't know of any plugins, but this site http://www.mcmaster.com lets you download a lot of their parts cad data.

Download as 3-D SAT it seems to work the best in max.

hope that helps
