🔌 Function

A tab washer sits under a nut or bolt head and has a tab that is bent over against the fastener and the mating component to mechanically prevent rotation. This keeps inlet and exhaust system fasteners tight despite engine vibration and repeated heat cycles.

⚠️ Common Signs of Failure

• Bent locking tab cracked, fatigued or broken off, leaving the fastener free to turn
• Fastener found loose or backed off during inspection
• Corrosion, scaling or pitting of the washer from exhaust heat and moisture
• Flattened or distorted washer body that no longer seats squarely under the fastener
• Exhaust or inlet leakage traced to a loosened joint at the washer location

🛠️ Service Notes

• Use a new tab washer whenever the turbocharger connection is disturbed.
• After applying the specified fastener torque, bend the tab fully against a flat of the retaining nut or bolt.
