Royal Enfield Classic, Bullet, Thunderbird, Himalayan & GT Genuine M6 Hex Nut | 586029/A

Genuine Royal Enfield Hexagonal Nut M6 × 1.0 – 586029/A

Royal Enfield Part Number: 586029/A

586029/A is a genuine Royal Enfield hexagonal nut with M6 × 1.0 metric thread. It is a shared OEM fastener used in multiple Royal Enfield assemblies across several motorcycle families.

This is not a model-specific decorative part. Royal Enfield uses the same genuine M6 nut in different locations depending on the motorcycle and parts diagram. Verified catalogue applications include older Classic 350 / Classic 500 UCE, Bullet 350 / Bullet 500, Thunderbird 350 / Thunderbird 500, Himalayan 411, Continental GT 535, and selected Continental GT 650 assemblies.

Important: compatibility means the nut is correct only at positions where the Royal Enfield parts catalogue specifically specifies 586029/A. Do not treat it as a universal replacement for every M6 nut on every Royal Enfield motorcycle.

Product Identification

Verified Royal Enfield Applications

Royal Enfield uses 586029/A in numerous chassis, body, exhaust and mounting assemblies. Verified catalogue references include:

Why a Small Fastener Still Needs Exact Part-Number Matching

An M6 nut may look generic, but thread size alone does not prove suitability for every mounting point. Royal Enfield uses several different M6 nuts, nyloc nuts, flanged nuts, washer-faced nuts and other fastening types across its motorcycles.

The correct replacement depends on the exact service position. A visually similar M6 nut can differ in:

• locking method,
• height or profile,
• flange or washer arrangement,
• specified mating hardware,
• service application,
• and the parts-catalogue requirement.

For this reason, order 586029/A when the motorcycle's EPC, workshop estimate or removed original part is identified by this OEM number.

Thread Specification – M6 × 1.0

The verified Royal Enfield description for 586029/A is Hexagonal Nut M6 × 1.

• M6 indicates a nominal 6 mm metric thread diameter.
• 1.0 indicates the 1.0 mm thread pitch used by this part.

This listing does not infer an unverified strength grade, coating specification, material grade, locking feature or torque value. Those details should be taken from the applicable Royal Enfield workshop documentation when they matter to the installation.

Earlier Part Number 141060

Older Royal Enfield catalogues used 141060 for an M6 nut in a number of applications. Genuine parts references identify 586029/A as the replacement part number for 141060 in those specified applications.

What About 586029/D?

Current genuine-parts databases also show a 586029/D reference with the same basic description, Hexagonal Nut M6 × 1.

However, the available evidence does not establish that 586029/D universally supersedes 586029/A in every historical 586029/A application. Therefore this product remains listed exactly as 586029/A.

If your VIN-specific parts catalogue calls for 586029/D rather than /A, order the exact required revision unless Royal Enfield's current EPC explicitly provides a supersession.

Examples of Where 586029/A Appears

Depending on the motorcycle, this nut appears in genuine Royal Enfield diagrams for areas such as:

• exhaust pipe and silencer mounting assemblies,
• front and rear mudguard assemblies,
• electrical-box and toolbox mounting,
• frame/body mounting points,
• side-panel related mounting on certain models,
• selected lighting/headlamp mounting assemblies,
• and other specific M6 fastening positions.

This list explains known catalogue usage; it does not mean one nut position is identical across all these motorcycles.

Classic 350: UCE vs J-Series Warning

The verified Classic 350 catalogue evidence for 586029/A comes from the older UCE-generation Classic 350.

Do not automatically assume that every fastener on the 2021-on J-series / Reborn Classic 350 uses this same part number. The newer platform has its own parts catalogue and should be checked by exact EPC reference.

Himalayan 411 vs Himalayan 450 Warning

Verified Himalayan compatibility found during research is for the Himalayan 410/411 generation. The Himalayan 450 is a completely different platform.

This listing therefore does not claim Himalayan 450 fitment unless the relevant Himalayan 450 parts catalogue specifically calls for 586029/A.

What You Receive

• 1 x Genuine Royal Enfield Hexagonal Nut M6 × 1.0
• OEM Part Number: 586029/A

Washers, bolts, studs, brackets or other surrounding hardware are not included unless separately purchased.

Installation Notes

• Confirm the service position calls for 586029/A before installation.
• Inspect the mating bolt or stud threads for damage, corrosion or cross-threading.
• Do not force an M6 nut onto damaged or incompatible threads.
• Use the relevant Royal Enfield workshop torque specification for the exact assembly.
• Do not reuse torque values from another location simply because both fasteners are M6.
• If the original assembly uses a lock washer, plain washer or another retaining component, refit the correct associated hardware shown in the parts diagram.
• For safety-critical components, installation and final inspection by a competent technician is recommended.

Before Ordering

Order this part when:

1. Your Royal Enfield parts catalogue specifies 586029/A; or
2. Your older catalogue specifies 141060 in an application where it is documented as replaced by 586029/A; or
3. The existing genuine fastener / workshop requirement has already been identified as 586029/A.

Do not select it only from the visual appearance of the nut or solely from the fact that a bolt appears to be 6 mm.

Frequently Asked Questions

A. Yes. Multiple Classic 500 UCE/EFI variants use 586029/A in specific assemblies.

Q. Does it fit Bullet 350 and Bullet 500?
A. Yes, genuine parts data confirms use on legacy Bullet 350 UCE and Bullet 500 applications, but the exact mounting location should still be matched to the parts diagram.

Q. Does it fit Thunderbird 350 and Thunderbird 500?
A. Yes. Both models' parts catalogues show 586029/A in several assemblies, including exhaust and body/chassis mounting positions.

Q. Does it fit Himalayan 411?
A. Yes, 586029/A appears in Himalayan 410/411 genuine parts references. Exact position must be checked in the relevant diagram.

Q. Does it fit Continental GT 535?
A. Yes, genuine parts databases show 586029/A in Continental GT 535 Euro 3 and Euro 4 applications.

Q. Does it fit Continental GT 650?
A. Yes, the GT 650 technical parts documentation shows 586029/A in selected assemblies, including a headlamp/lighting mounting position. This does not mean it fits every M6 position on the GT 650.

Q. What is part number 141060?
A. 141060 is an older Royal Enfield M6 nut reference. Parts databases document 586029/A as its replacement in the relevant legacy applications.
