Question: 1 / 445

Which of the following levels of tolerance indicates a higher precision?

General tolerance

Coarse tolerance

Fine tolerance

Fine tolerance indicates a higher precision because it defines very specific limits within which a measurement or a part must fall. In manufacturing and engineering processes, fine tolerances are crucial when components must fit together perfectly, such as in machinery where movement and alignment are key for proper operation. The narrower the range of acceptable measurement, the greater the precision required in fabrication and assembly.

In contrast, general, coarse, and loose tolerances allow for larger variations, which may be sufficient for less critical applications but do not meet the higher standards of precision required in many millwright tasks. These looser tolerances are more forgiving and accommodate a broader range of acceptable dimensions, which is not ideal for situations where accuracy and fit are paramount. Thus, fine tolerance represents the highest level of precision among the options provided.
