Have never heard of a TTY bolt, but I learn something every day.

  By definition, those types of bolts are Torque to Yield (TTY) which means they are torqued to their yield strength and are no longer in the linear portion of their Yield Strength curve, i.e. they are no longer follow Hooke's Law. 

  Cliff's Notes: They can't be reused, 'cuz if done properly before, they've yielded.

    As an engineer we learned in school that steel will stretch and return to
    its original length without damage unless you hit the yield point of the
    curve.  So, why can't they be reused as long as they are kept in the Hook's
    law range of the yield?  I don't intend to reuse them, but don't see why
    not.
