SOLD AS A SET OF 4 PCS

Royal Enfield RAN00402/B Bolt, Dome, M8 x 25, 8.8 is a genuine Royal Enfield dome-head bolt used in catalogue-matched lighting and instrument cluster hardware applications. It is commonly searched as a Royal Enfield dome bolt, M8 x 25 bolt, headlamp bolt, instrument cluster bolt, lighting bracket bolt, dome cap bolt or RAN00402 bolt.

This is a small but important factory hardware part. Front lighting, headlamp casing, instrument cluster, brackets and nearby body assemblies often use specific bolt lengths, head shapes and strength grades. A wrong local bolt may be too long, too short, wrong thread pitch, incorrect head profile or poor grade, which can cause loose fitment, damaged threads, scratched painted parts, vibration noise or poor front-end assembly alignment.

Public Royal Enfield parts references identify RAN00402/B as BOLT, DOME, M8 X 25, 8.8. International dealer references place it in the Lighting & Instrument Cluster parts group, while seller references also list the RAN00402 dome cap bolt family for selected Bullet / Classic / NTB applications. This listing is therefore written as a part-number-led genuine hardware listing rather than a broad universal bolt listing.

Use this genuine Royal Enfield bolt only where RAN00402/B, RAN00402/A or the RAN00402 Bolt, Dome, M8 x 25, 8.8 reference is specified in the exact parts diagram. This is not a full headlamp assembly, not a nacelle, not a headlamp rim, not an instrument cluster, not a washer kit, and not a generic hardware pack.

Important Fitment Note

This listing is for one dome bolt unless a different quantity is selected. It is not a complete headlamp assembly, not a headlamp rim, not a headlamp nacelle, not an instrument cluster, not a bracket, not a washer/spacer kit, and not a complete front-end hardware kit.

Do not order only by approximate size. Royal Enfield uses different bolts across lighting, body, frame, engine and bracket assemblies. Even if another bolt looks similar, length, grade, head profile, thread pitch and finish may differ. Match RAN00402/B in the exact parts diagram before purchase.

Do not use this as a universal M8 bolt for every motorcycle application. For safety-critical frame, suspension, brake or engine positions, always use the exact bolt part number listed in the relevant parts diagram.

RAN00402/B vs Other Front-End Parts

When Should This Bolt Be Replaced?

• Original dome bolt is missing after repair or bodywork
• Bolt head is rounded, scratched, rusted or damaged
• Incorrect local bolt has been fitted in the lighting/instrument cluster area
• Headlamp or front-end assembly is loose due to wrong hardware
• Front-end restoration needs correct genuine Royal Enfield hardware
• Old bolt does not tighten correctly or has damaged threads
• Workshop wants OE hardware instead of mixed local fasteners

Why This Part Matters

Small hardware affects repair quality. A wrong bolt in the headlamp or instrument cluster area can create vibration, uneven fitment, scratched painted parts or a visibly non-factory repair. Using the correct genuine Royal Enfield RAN00402/B helps maintain the intended front-end assembly finish and correct hardware specification.

Recommended Related Parts to Check

• Matching washers or spacers used in the same assembly
• Headlamp bracket / nacelle mounting area
• Instrument cluster bracket condition
• Thread condition in the mating part
