OVERVIEW

Genuine VW/Audi panel screw, part number N-103-546-02. This original internal six-lobe fastener is used at multiple factory panel attachments. The table below identifies confirmed underbody and engine protection pan applications using this specific screw.

Technical details

  • Original part number: N-103-546-02 / N10354602.
  • Published nominal screw size: 5 x 16.
  • Internal six-lobe drive and broad head contact surface.
  • Panel screw; do not substitute a machine-thread M5 bolt solely on nominal diameter.
  • Earlier cataloged number: N10354601.
  • One screw supplied. Cover, pan, retaining clip and other hardware are separate.

At the specified attachment, the screw retains the underbody cover against its original mounting point. The correct fastener and an intact mating clip help keep the cover seated without damaging the mounting hole.

Different screws can be used around the same pan or cover. Match the original number and location, including screw length, head form and the mating clip. This listing does not supply a complete cover hardware set.

Common reasons to replace

Replace a missing screw, stripped drive recess, damaged thread, bent fastener or corrosion that compromises its condition. Routine oil service and underbody access can expose lost or damaged screws that should be corrected before the cover is refitted.

A loose cover can rattle or move when its hardware is incomplete. Inspect the retaining clips, panel holes and mounting points rather than repeatedly tightening a screw into a worn or damaged attachment.

A replacement screw will not repair a cracked belly pan, torn mounting hole, missing clip or bent support. Repair the damaged mating component so the new hardware can retain the panel correctly.

Installation and service notes

Support the vehicle safely and identify the exact cover attachment before removal. Keep track of different screw types and their positions. Compare the original fastener with this part number before ordering.

Align the cover with its factory mounting points and make sure the specified retaining clip is present and undamaged. Engage the correct screw carefully with a properly fitting six-lobe driver.

Follow the applicable tightening instructions for the cover and clip arrangement. Do not determine torque from the nominal 5 x 16 size, substitute a longer screw or use excessive force to compensate for damaged plastic or a stripped clip.

Check that the panel sits correctly and that the required hardware is installed at every mounting point. If a screw spins without retaining the cover, inspect the mating clip and attachment instead of overtightening.

This small replacement fastener is sold individually. It does not include an oversized body panel, a replacement underbody pan or a complete installation kit.
