I bought a quick release joint from Atlas several months ago. I've never installed one before. It's not a uniloc. I'm at work or I'd post a pic. It has a ball on the end of the pin. Anyway, what tap do I need for the insert? It seems to be larger than a 7/16-14. The pin is the same thread as a weight bolt, 3/8-16 or what ever. Hope this is enough info, if not I'll do some measuring when I get home.
