Technical details
- Original number: N-911-664-01 / N91166401.
- Published nominal metric diameter and length: M6 x 14 mm.

- Confirmed application: interior lamp assembly retaining bracket.
- Selected vehicle diagram reference: position 15.
- Bracket, lamp assembly, trim and other hardware are separate.
The bracket provides the prescribed attachment arrangement for the interior lamp assembly. The screw belongs at its assigned fastening point. It does not replace the retaining bracket or repair damaged lamp or trim mounting features.
This original number is used in multiple vehicle assemblies. The fitment table here describes the confirmed interior lamp retaining bracket position, so identify the actual location before ordering. A general catalog association with a vehicle does not establish every screw position on that vehicle.
Common reasons to replace
Inspect the screw when removing the lamp assembly, its bracket or surrounding trim for service. Replace damaged threads, a rounded drive recess, a bent screw or corrosion that prevents proper installation. Renew removed hardware when prescribed.
Previous work can leave a missing screw, a mismatched fastener or damage from an incorrectly fitting tool. Check the original number and fastening point before ordering. A screw that appears similar is not sufficient confirmation of correct length and bearing arrangement.
A loose lamp or bracket requires inspection of all attachment points. A new screw cannot repair a broken bracket, stripped mounting point, cracked lamp housing or damaged trim. Correct the diagnosed condition before securing the assembly.
Rattles and interior lamp operating faults can have causes beyond this fastener. Inspect the bracket, lamp assembly, connectors and surrounding trim as appropriate. A mounting screw is not a replacement bulb, switch or electrical control component.
Installation and service notes
Follow the factory procedure for the installed overhead lamp and equipment arrangement. Identify the retaining bracket and assigned screw position before removal. Use suitable trim tools where prescribed to avoid damaging the surrounding interior surfaces.
Handle lamp wiring and connectors carefully during access. Follow the required electrical disconnection steps for the operation being performed. Do not allow a suspended lamp assembly to load or strain its wiring.
Inspect the bracket, mating surfaces and threaded attachment point before fitting the new screw. Seat the bracket and lamp components correctly. Do not tighten the screw to compensate for a cracked bracket or misaligned trim.
Start the screw by hand and use the correct fitting six-lobe bit. Keep the tool aligned with the recess. Stop if the screw binds before seating and check the part selection, thread condition and alignment rather than applying additional force.
Use the specified fastening procedure and torque for the interior bracket position. Do not transfer a tightening value from a different application of this original number. Apply thread treatment only when called for by the factory procedure.
Confirm the installed lamp equipment and bracket arrangement, especially where a lamp assembly or surrounding trim has been changed. Factory vehicle fitment does not establish compatibility with every aftermarket lamp or conversion.
Reinstall the surrounding components as prescribed and check that the bracket, lamp and trim are secure. Verify normal lamp operation after reconnecting disturbed electrical components. Order the quantity required for the positions being serviced; one screw is supplied.
