Use go/no-go gauges to verify thread integrity before installation; reject connectors with damaged, deformed or cross-threaded surfaces to avoid assembly failure.
Align the locating pin first, hand-tighten the connector to ensure proper engagement, then apply a torque wrench to reach 60cNm for secure locking without over-tightening.
Technical Note: Do not use excessive force to tighten mismatched threads – this will damage both the connector and equipment interface. Apply anti-seize compound for connectors used in high-vibration environments.
