Technician's Advisory: Expanding nuts come in several sizes across the Audi and Volkswagen ranges — the wrong size spins or splits the mounting hole. Always confirm exact fitment with your VIN before ordering — our team verifies compatibility before dispatch. Tighten to firm hand-tight only; overtightening destroys the nut and can crack the panel.
FAQs
xFrequently Asked Questions
The expanding nut is a blind fastener: pushed into a panel hole, it expands as the screw tightens and grips from behind where no nut can be reached. It anchors trim, undertrays, wheel-arch liners, and bumpers to the body. When the old nut spins or crumbles, panels hang loose and rattle — the genuine N90821401 restores the factory mounting point.
A failed expanding nut shows as loose trim: undertrays that sag, wheel-arch liners that flap at speed, or screws that spin without tightening. You may hear rattles from the wheel wells or see a bumper edge sitting proud. Because the nut hides behind the panel, the screw never bites — replacing the nut is the fix, not a bigger screw.
This is a genuine Audi Volkswagen fastener, but expanding nuts come in several sizes — the wrong size spins or splits the hole. The safe check is your VIN. Send us the full 17-character VIN before ordering and we will confirm the exact fastener for your panel. At this price, ordering the verified one beats a box of wrong sizes.
For a fastener, yes. Aftermarket expanding nuts often use brittle plastic or the wrong expansion range, so they crack during fitting or spin the first time the screw is removed. The genuine N90821401 expands evenly and survives repeated removal. At this price, the genuine part costs little more than a copy and holds the panel properly for years.
This is a brand-new genuine Audi Volkswagen part in factory packaging, covered against manufacturing defects under the standard genuine parts warranty. Your statutory consumer rights apply in the UAE. If it arrives damaged or incorrect due to our error, we replace or refund it. Share your VIN before ordering so the fastener size is verified for your vehicle before dispatch.
