DIN screws/bolts and nuts

Library to create metric screws according DIN912 (socket head) and DIN933 (full thread hex bolt), nuts according DIN934 (hexagonal nut), DIN439B (hex nut flat) and a sketch for 
DIN125(washers).

I know.. just another library for something that every CAD has build in.. but.. for me it was actually easier to write it myself.. so maybe somebody still might find it useful.

The bolts and nuts are more or less complete, just the dimension tables are not in place, you will need to fix xxx_table.scad file with data for your desired dimension. Sorry I didn't have the patience to copy it. Maybe one day I will do that.

The washer file is just a “quick sketch”, but still it might save some time.

The din_nuts.scad and din_screws.scad are the actual nuts and bolts.
The xxx_table.scad are functions that should provide data from the ISO norms.
The round_xxx.scad are helper shapes to form the nuts and bolts.
The ISOthread.scad is the ISO thread library from RevK.

Note:
Seems like the ISOthread.scad does not exactly match the actual metal store bought parts “super perfectly”. Still with a decent force it's usable. Maybe one day I will find more suitable library for the threads or maybe you can create your own.
