Fast threads

[stel8]

I am looking for special threads used for quick opening of jars, bottles, etc. I am interested in standards and specifications, and also in calculations of forces, friction, etc, for different materials with such threads.
Thanks for any ideas.

Check out multiple lead threads. They are favorable for all the mechanical props that you listed.

I agree multi lead threads is good. Machinist Handbook has wide varety different thread types (light bulb etc..).

If you have a good machine shop they can offen design one or copy one for you.

Good Luck & Happy New Year!!
