Thanks for the diagram, Enthalpy - makes sense.
The screw in consideration already has a centre hole which is used for lubrication feeds. Unfortunateley, altering the diameter of the internal hole is not acceptable in this application, as it will restrict the oil feed.
The tapred nut...
Wow!
Thanks, all of you :)
I'm overwealmed by the support and informative responses I've got. All useful information, despite me not doing the best job of describing my situation.
I have made some initial calculations based on the idea of un-coiling the thread contact area into a 2d...
Thanks Guys.
Dick L: Are you sugesting that I simply, calculate the circumferance of the inner and outer diameter, average the two for an x dimention, then use the incline in one thread revolution as a y dimention, and work out the full thread distance by pythagerous?
Will that be accurate...
hmm, no response... Am I missing something?
Did I not make my question clear, which is - What is the best way to go about deriving an acurate formula for the upward facing area of a heliacle screw-thread?
Am I posting this in the wrong forum. If you think there's somewhere else I may get a...
Guys, I have a similar issue where I'm trying to calculate the contact surface area on a threaded bolt. Any there's an added level of complexity as the helix has surface area.
Any help would be great.

I'm trying to determine the contact surface area of a threaded bolt so that I can make some changes to the design and maintain the same contact surface so as not to affect the performace in other ways.
This presents itself as a helix, and my initial guess was that it may be best to work this...
