The Royal Enfield Flanged Hexagonal Bolt – 574038/B is a model-specific fastener used in designated motorcycle assemblies.
Its hexagonal head allows tightening with a suitable tool, while the integrated flange distributes clamping force over the mounting surface. The 85 mm length and M6 × 1 thread specification are important when matching the replacement bolt to the original.
