Knurling bolt and nut

****** I added two .f3d files made in a simple way on Autodesk Fusion 360. - new_knurling_bolt_01.f3d - new_knurling_nut_01.f3d ****** I published [Yet another knurling bolt and nut](https://www.thingiverse.com/thing:3179814). ****** I uploaded Fusion360 (.f3d) files and step files. ****** An image of the tolerance between the nut and bolt was uploaded. Only measured on 3dcad. See at last thumbnail. ****** There are knurling bolts and a nut that modeling on Autodesk Fusion 360. I got a inspiration form [Knurled surface finishing library](http://www.thingiverse.com/thing:9095) by [aubenc](http://www.thingiverse.com/aubenc/about). Thanks! I've prepared a bolt of various lengths. So, print a bolt you want. Bolts are M16, pitch 2.0, length 20, 30, 40, 50, 60mm, and Head OD 30mm, height 20mm. A nut is M16, pitch 2.0, height 20mm.
