Thread forming taps

[jeremy13]

I wanted to try a thread forming tap, I found the formula for the predrilled hole. But wear do you find the information for the percentage of thread engagement for a particular application. This will be in 6061 aluminum for a JIC fitting operating at 500psi

I would call the folks who make the tap, they know thier stuff and some time you get to talk to a flirty gal who is cool. :D

Jeremy,
Cant help you with a formula but if you tell me the tap size I will attach a picture with all that information shown.
