If the high limit is 0.502 inches and the low limit is 0.498 inches, what is the tolerance?

Explanation:
Tolerance is the total amount of variation allowed between the largest and smallest acceptable size. With a high limit of 0.502 inches and a low limit of 0.498 inches, the range is 0.502 − 0.498 = 0.004 inches. That 0.004 inches is the tolerance. The nominal size would be the midpoint, 0.500 inches, so the part is allowed to vary ±0.002 inches around that nominal point. So the tolerance is 0.004 inches (with a ±0.002 range around the nominal).
