fast self-filetting

Hello, everyone.

Is there a way to draw it? using helical protrusion maybe?

Thank you.

I'd say it's the only solution.

Bye.

I made a screw with normal thread (by setting the value of the hole necessary because threads) and then I added a non threaded cone representing the tip.

using protusion is fine if I have to model a screw for a factory making screws
If such a life I put it in a set that counts 50... all snaps a little.

You must always draw what you need! (what learned in time)

I'm not sure exactly, but maybe you could use it.

I have 2000 pieces and snaps already without screws!

I've been looking at the pictures, and I understand why you put two protrusions in the dot? Thank you.

cause computer formatting I couldn't open the original nik name siou so I sent the pictures as robimail . Now the administrator should have provided to delete robimail.
after this pecisation I answer your question:
the helical protusion 1 has a strip inside of 22.5°
while protusion 2 has a strip of 45 ° to close the protusion in the cone of the screw.
I have many doubts that in reality the screws in question are built like this.
I wanted to try!!!!!!!!!! However if you read: http://www.cad3d.it/forum1/showthread.php?t=6522&highlight=viti+autofilettantigerod recommends to me the best thing.
