Bolt/Nut/Thread Generator

I was playing around with trying to make a bolt on my 3d printer and came up with template of sorts for making both Bolts and Nuts. 

This is effectively a screw generator for METRIC sizes. 
It might work for IMPERIAL but I have not tried. 
I'm not an engineer and most of this was done with just a few hours of research on the web. For those of you who maybe know a bit more than me fell free to correct any terminology I may have wrong.

To use; duplicate the parts studio, and edit the values for "Whole Word" variables only. The variables that are not whole word are used in calculations and/or may contain calculations. Editing them will most likely break things.

I developed this to create and print nuts and bolts on my 3D printer. As such the Tolerances have to be much greater than real machined threads. The bolts and nuts I have produced with this work with a machined thread checker I purchased from Home Depot. I have not  tried to create a machined nut or bolt as i don't have the equipment.

Below are the values that should be edited along with a brief description of what  the value represents.

Tolerance: The oversize/undersize of the threads.
WrenchSize: The size of the wrench the head will fit.
HeadDepth: The depth or height of the head.
ThreadLength: The distance the shaft protrudes out of the head.
Diameter: The diameter of the shaft.

    I like this. I tried to suggest that OS provide a library system for peramterize parts. Looks like we do it ourselves or wade through the online parts. I've take a copy ( best  compliment!) and tweaked it a bit to give more realistic chamfer.

    See it at https://cad.onshape.com/documents/1ad23a33342bff8f643010b7/w/6760e27dffcb0b79bf00708b/e/cc7ad52df3807e51693f78a3

    There is a "feature" in the bolt thread that i have proposed an update unless you beat me to it!

    I haven't fully tested it so have fun!!

    For metric bolts there are standard ratios so picking a  bolt size(diam) drives the head size and gives 2 thread pitch options... then you get to choose the length.

    Genius, this helps me with modelling bolts AND understanding how Onshape’s parametric system works.

    Thanks for sharing!
