I modeled this bolt with extra care.
All polygons are quads.
Except *.3ds format, where 3DS specification makes all the quads in triangles.

If you plan to import this model in other software than Cinema4D i would suggest you to use OBJ file format witch handles quad polygons very well.

Because all the polygons are quads you can easily transfer this model between the programs.

Thank you for viewing my model,
