Fastener size request #382

Open Qmodo opened 1 month ago

Qmodo commented 1 month ago

Hi there! There's a fastener size that's currently not available in the workbench that I would appreciate being added! For the DIN603 (Mushroom head square neck bolts) the minimum size available in the workbench is M5, however, I've got M4 and M3 sizes that I'd like to be able to include in my designs. These are available from several stores, so it would be great to have them added!

Edit: Same goes for the EN 1661 (Hex nuts with flange). It would be great to have the less mainstream fasteners all go down to M3 since those sizes are pretty common on things like 3D printers.

In the DIN 603, M5 is the smallest size specified. There for it can not be guaranteed that other sizes are available, since they are not standard.

That does not mean that I have a problem with including them, but they should be labled as Not standard(NoS), same as I said in #377

That seems like a pretty fair solution! I didn't realize those weren't standard. Thanks for the response

Usually non standard sizes are marked with parenthesis such as (M4) (m3) etc

Bit I am pretty sure that the DIN and ISO standards uses this way to mark not recommended sizes.
