0.001
0.003
0.005
0.007

The correct answer is: 0.003

In the context of a standard universal pin kit, the graduation length refers to the incremental value by which the pins are measured and sorted. For a pin diameter of 0.115 inches, the commonly accepted graduation length is 0.003 inches. This precision allows locksmiths to create highly accurate pin stacks for various lock mechanisms, ensuring proper function and security. Using this specific graduation length, locksmiths can identify the correct height of each pin and effectively combine them to tailor lock functionality according to specific needs. This standardization in pin sizing helps in maintaining compatibility across different locks and simplifies the process of pin selection for locksmiths.
