Plastic Nut – Mopar (6510393aa)

Factory part number 6510393aa: a plastic nut supplied by MOPAR. It is catalogued under Nuts & Washers > Nuts.

• Flange nuts distribute clamping load without a washer, so a plain nut at the same torque will mark the component.
• Where a nut is also a sealing element, as on a fluid line, the thread form is part of the seal rather than a fastening detail.
• Washers used under aluminium or plastic are usually larger in outside diameter to spread load, and a standard washer will dish the surface.

Nylon-insert lock nuts lose their prevailing torque after a single removal and should be replaced rather than reused.

Check the number on the part you are removing before ordering. If it is worn off, send the VIN and a photo and we will match it. Ships from our US warehouse in one to two business days, free over $59.
