Locks a stud or bolt with an integral flange that spreads the clamping load across the joint face.

⚠️ Common Signs of Failure

• Joint loosening between services
• Flange serrations flattened out
• Thread stripped or crossed
• Nut corroded onto the stud so it shears on removal

🛠️ Service Notes

• This is the earlier-production nut - check your engine serial number against the 7009156810 breakpoint before ordering, since later engines take a different part
• The number it replaces was listed as a plain nut, so confirm whether a separate washer was fitted with the original
