Should I
toss buttress threads in? Or the whole family of oilfield
tool joint technology? Those are threaded pipe couplings meant to be
torqued to 50,000 ft/lb and more. You oughta see the pipe-wrench....
I bet you
don't drop that pipe-wrench on your foot :)
What do you call the type of thread used for adjusting the size of pipe
wrenches (and Crescent wrenches)?
If nobody objects to something ON-topic:
What would you call the thread of the lead screw on a Micropolis 100TPI
drive?
