Zafety Lug Lock Turbine

Preventing Bolt Loosening and Turbine Damage

Engineered to secure nuts in high-vibration environments, the Zafety Lug Lock Turbine prevents bolt loosening. Zafety Lug Lock Turbine units are installed over two adjacent nuts/bolts, creating resistance between the nuts/bolts to minimize their ability to rotate and prevent them from loosening.

Zafety Lug Lock Turbine units reduce the risk of nut loss or bolt loosening, vibration damage to other turbine parts and more catastrophic outcomes like wing loss.
