Glenn Beale had this article long time ago: http://www.plasticstoday.com/articles/design-molded-threads%E2%80%94part-3
But the figures don't display on the web site. The article is useless without them. Anyone know how I can get a copy of:
"Figure 5. A reliable method of specifying a molded plastic thread."
I'm tired of banging my head against the wall talking to very good engineers who just don't think a different spec for plastic threads matter. If I had a picture.....

Hmmm. You're right. Been six years since that was posted, probably a case of broken links as the website has been updated.
I'll see if I can track them down, but they just may no longer be accessible.
If you forward your email address to me, I'll let you know if we can do anything.
