Screw-O-Matic Bolts Generator | Substance 3D Designer Custom Nodes

Hey!
I'm working on a Github repo to share some of my custom nodes made in Substance Designer to speed up Material and Texture Creation process!

If you find it useful you can download these nodes for free, the Repo is public and completely open!
Let me know what you think, can't wait to see all of you collaborating on this project.
Cheers!
