Answer:
Step-by-step explanation:
The longest acceptable bolt is one that is longer than the mid-range value by an amount equal to the difference limit, 0.2 mm
12 mm + 0.2 mm = 12.2 mm . . . . longest acceptable bolt
The shortest acceptable bolt is one that is shorter than the mid-range value by an amount equal to the difference limit.
12 mm - 0.2 mm = 11.8 mm . . . . shortest acceptable bolt
