Using the 3d modeled bolts, screws, rivets and several other mechanical props I built for a project of mine,
I decided to make a set of  ZBrush brushes for my projects and to share it with the community of  ZBrushers

So, here it is, a pack of totally 50 different brushes for your  ZBrush creations. You can download them in the Freebies section,  as 2 zipped files,  one with the actual brushes and one with the alphas only.

Please do not hesitate to link to the following packs. In case you use these brushes in a commercial project,
I would appreciate it if you give me credit for my work.

Have fun with them!
