Question

Quizplus · Accepted Answer

None of the options provided specifically describe a thread that fits and seals tightly by definition alone. The ability of a thread to fit and seal tightly depends on its design, application, and whether it is combined with sealing mechanisms such as O-rings or Teflon tape, rather than the thread standard itself (Metric, Whitworth, Unified, American National).
