N-909-591-01 Genuine VW/Audi Speed Nut - 5 x 16.5 x 11

Genuine VW/Audi retaining speed nut, part number N-909-591-01. This original clip nut provides the matching screw attachment at assigned rear bumper and underbody panel positions on the configurations below. Match the original clip number, panel seat and screw before ordering.

Technical details

• Original number: N-909-591-01 / N90959101.
• Published nominal designation: 5 x 16.5 x 11.
• Folded clip form with a screw-retaining opening.
• Listed application: specified rear bumper hardware position on the Mk5 GTI.
• Bumper cover, mating screw and other mounting hardware are separate.

The retainer clips onto its assigned mounting edge so the specified screw can secure the adjoining component. Its shape and seating depth position the retaining opening relative to the panel. Match the original clip and screw arrangement; this is not a conventional machine-thread hex nut.

The nominal designation identifies this particular retainer. It does not establish suitability for every panel or screw of a similar size. Different attachment positions can use different clips, screws and mounting depths even within the same bumper assembly.

Common reasons to replace

Inspect the clip during bumper cover removal, refitting or repair of loose mounting hardware. Replace missing clips, damaged screw-retaining features, bent retainers or corrosion that prevents correct seating. A clip that no longer holds its assigned position should be renewed.

Previous work may leave an incorrect retainer or a screw that has damaged the retaining opening. Check the screw as well as the clip before reassembly. Selecting the correct pair helps restore the original attachment arrangement.

A loose cover, uneven panel gap or rattling attachment requires inspection of the complete mounting area. A new speed nut cannot repair a cracked mounting tab, broken bracket, distorted cover or damaged seating edge. Repair the diagnosed support or panel defect before refitting the hardware.

Installation and service notes

For underbody panel service, inspect the panel and clip seat for damage. Position the clip fully in its assigned mounting location, align the panel without forcing it, and start the correct screw by hand. Replace a distorted clip or damaged panel attachment rather than overtightening the screw.

Follow the factory procedure for the exact bumper and trim arrangement. Identify the original clip position before removal and compare its shape, seating depth and screw location with N90959101. Preserve the prescribed order of the surrounding brackets and panels.

Inspect the mounting edge and remove damaged hardware using the approved method. Fit the retainer in its specified orientation so it seats correctly and the screw opening aligns with the adjoining component. Do not force a clip onto an incompatible panel thickness or damaged attachment.

Use the prescribed screw and start it carefully through the correctly aligned assembly. Do not use an oversized screw to compensate for damaged retaining features or use the screw to pull a misaligned cover into place.

Follow the factory tightening requirement for the actual panel attachment. Excessive tightening can damage the retainer, screw or surrounding mounting tabs. If the screw spins without holding, inspect the clip, screw and seat instead of continuing to tighten.

Check the completed attachment for secure seating, proper panel alignment and the required clearances. Inspect the other mounting points disturbed during service. This listing supplies one original speed nut; obtain the mating screw and other repair components separately.

Fitment

Confirm original N90959101 and the assigned rear bumper clip position before ordering. One retainer supplied.
