⚙️ Key Features

• 0.050 kg

🔌 Function

Locks the nut or bolt against rotation so vibration cannot slacken the joint.

⚠️ Common Signs of Failure

• Fastener found slack on inspection
• Tab already bent and straightened, or cracked at the fold
• Washer flattened so it no longer springs
• Corrosion between washer and mating face

🛠️ Service Notes

• Lock washers are single use - fit a new one rather than bending the old tab back
• The lighter lock washer 853160, at 0.009 kg, is the Drive unit 290 part and is not interchangeable with this one

📦 Condition

• Brand new
• Supplied in original or equivalent packaging
