This lock nut is designed to securely fasten components in automotive applications, typically in areas like exhaust systems or engine mounts, preventing loosening due to vibration or thermal expansion.
OE-quality means the part is manufactured to meet or exceed the standards set by the original equipment manufacturer, ensuring it performs and fits like the original part.
You should consult your vehicle's service manual or a parts catalog specific to your car's make, model, and year. You can also compare the OEM part numbers listed in the product description with those in your manual.
While it has an M7x1x8,3 thread, it's specifically designed for OE applications listed. Always confirm compatibility with your specific application to ensure proper fitment and function.
The Goods tariff number (7318160085) is a harmonized system code used for international trade and customs classification of goods.
The alternative repair kit number mentioned is 812.410. It may be useful for specific repair scenarios.
Verify the thread size (M7x1x8,3) matches the bolt/stud. Ensure the bolt/stud threads are clean and undamaged. Check for any cross-threading from previous installations.
Stop immediately. This usually indicates a thread mismatch or damage to either the nut or the bolt/stud. Inspect both for damage and replace if necessary. Ensure proper torque specifications are being followed.
Ensure the nut was tightened to the correct torque specification. Some applications may require a secondary locking mechanism or thread-locking compound if vibration is excessive.

Compatibility:
This lock nut is designed to be a direct replacement for several OEM part numbers across BMW, Mercedes-Benz, and Toyota. Always consult your vehicle's service manual or a qualified mechanic to confirm the correct part number for your specific make, model, and year.
Care:
As a component typically installed in high-heat and demanding automotive environments, no specific ongoing care is usually required beyond ensuring it remains properly tightened. If components are disassembled for other maintenance, inspect the lock nut for signs of wear, corrosion, or damage. If any damage is observed, it should be replaced immediately.
