I'd like to make ISO4035-like M5 nut 1 mm long unfortunatelly it has fixed lenght of 2.5 mm. "Nominal lenght" value doesn't work unfortunatelly. Can anyone answer how to add a custom nut to list?

OK, I've just re-scaled it successfully. An easy solution.

Hello, I love this macro but I needed to have left handed threads so I've modified the code to implement it with a checkbox.

Hope you like it and if there is any bugs, feel free to reply with the error so I can modify the code to fix it.

Hello,

I'm Daniel from Germany and this is my first post here.

Since now I have the Screw Maker Macro and I like it very much.

I want to creat a new ISO 7380 Screw with a flat Head. Is this possible?

Thanks a lot

Daniel

Are you using the version posted here: memberlist.php?mode=viewprofile&u=1928
This version has ISO 7380 Screws.

Yes I use it and I also found the ISO 7380 screws but I have to make a Head with a bigger Radius but flat, like in the picture.

I think its Not easy to creat a new Screw in the macro right?

This depends on the type of the screw.
I programmed only screws, which are defined by an official standard. It will be an endless task otherwise.
The screws on the picture look like something different than ISO 7380. They have a diameter of the shank much bigger than the thread. Exist a standard for these type of screws?

That seems to be a special locating screw, the german system DIN 173 describes screws of that kind, although they don't have such a big diameter for the head. ISO 7379 is similar (shoulder screws) but they have a hexagon head.

@ ulrich1a: Really great screw maker makro .... WOW !!!!

The metric iso threads are (unfortunately) not very useful for 3d printed threads.
Therefore i am using my customized thread profile which works pretty well and functional.
The picture shows custom M24 inner thread with 5mm pitch.

How is it possible to generate such custom thread profile with your script?
I want to generate different size and lenght with ISO head.

Would be great if you could help me! THANKS
