Royal Enfield M6 Hex Flange Nut – 574126/A – Genuine OEM

Genuine Royal Enfield M6 × 1 hex flange nut used across multiple Royal Enfield assemblies. The model-specific Royal Enfield EPC description is “HEX FLANGE NUT, M6 X 1”. Buyers may also search for it as an M6 flange nut, M6 flanged nut, M6 captive-style mounting nut or Royal Enfield mounting nut.

This is a common OEM hardware part, not a single-model decorative component. The same base part number appears in several Royal Enfield systems including lighting/instrument mounting, electrical mounting, oil-cooler assemblies, fuel-tank mounting, rear-mudguard assemblies and engine/cylinder-barrel applications.

Part Identification

Important Catalogue Description Conflict

Some Indian Royal Enfield spare-parts price-list data has shown 574126/A with an inconsistent “M12 × 1.5” description. However, multiple Royal Enfield model-specific exploded parts books and current genuine-parts dealer catalogues identify 574126 / 574126/A as an M6 × 1 hex flange nut.

This listing therefore follows the model EPC / actual application description: M6 × 1. If the physical genuine packet you receive carries a different specification, stop and verify it before installation.

Verified Guerrilla 450 Application

In the Royal Enfield Guerrilla 450 lighting and instrument-cluster parts book, base part 574126 appears as HEX FLANGE NUT, M6 X 1.

Therefore, do not assume one universal Guerrilla 450 quantity. The required quantity depends on the exact front instrument configuration.

Other Confirmed Royal Enfield Applications

574126/A is a shared genuine fastener. Verified catalogue examples include:

This table gives verified examples, not an exhaustive compatibility list. Because 574126 is a general OEM fastener, additional Royal Enfield models and assemblies can use the same nut. Always match the exact EPC position before ordering for an unlisted application.

Why the Same Nut Appears in Different Places

Royal Enfield reuses common standardised fasteners across many assemblies. The same M6 flange nut can therefore appear in a cylinder-barrel diagram, an electrical bracket, a fuel-tank mounting diagram, an instrument bracket or a mudguard assembly.

The part number determines the fastener specification; the assembly determines how many pieces are required.
