Look it up in the Machinery Handbook. Titanium is so brittle I can't imagine what you would want to use it for. Use trial and error, put one in a vice and see on a torque wrench where it brakes , then go only half of that and you will have the right amount of torque.

Grade 2 is pure titanium (not alloyed)....inferior in strength to the cheapest steel bolt. Alloyed titanium bolts are superior in strength to most steel....widely used in the aircraft industry.

Catch ya later.
yup its not much stronger than 7075 aluminum. i'm using lots of aluminum bolts or nuts in my car, where strength/safety is of no concern. found lots of cheap 3/8" ti bolts and thought i could replace the intake/exhaust bolts but 30 ft/lb wont do.
if titanium behaves like steel its hard to tell when it breaks. usually only the threads shear which is hard to tell when exactly.
