An image of the tolerance between the nut and bolt was uploaded.
Only measured on 3dcad.

***< SUMMARY >***
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.
