DIY Balsa stripper

I wouldn't worry about this issue, George.

McMaster-Carr seems to have plenty of suitable metric nuts and screws in suitable sizes: www.McMaster.com. 
They are a very big supplier of hardware in the USA and will supply hobbiest scale orders in my experience.

Thanks, Jeremy, you've reminded me - it was McMaster-Carr whose catalogue is embedded within Fusion 360. Inserting any of their very extensive range of bolts and widgets into a CAD design is thus made extremely easy. Anything similar in your CAD weapon of choice, Andrew?

I think the question from George was what nuts & bolts would a typical modeller in USA find in a typically USA modelling shop. It will be useful if we can get an input from someone 'on the ground'.

Yes they are in Inventor, but just by designation and standard and not by a "commercial sponsor". Inventor is the more advanced industrial version of Fusion 360 (ie a product of Autodesk)

Hi, sorry for the radio silence the past few days, I was away and although I could read, I could not properly reply.

Thank you all for your replies, it seems I opened quite a big subject. All answers were useful but would require further searching, which Steve spared me from, more or less.

I could have left the STL files as they are for US modellers. It is a simple thing to find a fitting screw to pass through the 3mm hole. The problem is/was, that I have the nuts embedded in the plastic parts to be fixed inside a hexagonal cut and if they are bigger they will not fit.
But now I have this information and I can check and modify accordingly.

My CAD does not have a fastener database, neither in metric nor in US units.

So I d' better complete the article now as is. I have some time to add the STL files to the Plans Gallery.

Thank you all for your replies and help!

George
