Description

  1. TASK 70-42-00-400-501 Locking Devices General Information

    1. General

      1. The primary use of a locking device is to work against the force that causes two parts to become loose. It does not help to keep the necessary torque values. Because the effect of such a device is directly related to safety, it must always be correctly applied.

      2. Locking devices are:

        1. Key washer (see 70-42-03)

        2. Cup washer (see 70-42-04)

        3. Lock wiring (see 70-42-05)

        4. Staking (see 70-42-06)
