Genuine Royal Enfield Rocker Cover Flange Bolt for Interceptor 650 & Continental GT 650 BS6 (Part No. 575248/D)
Product Description
Precision-Engineered Shoulder Profile: Features a distinct collar design that acts as a physical stop, preventing over-compression of the fragile rubber valve cover gasket.
Integrated Flange Washer Face: Spreads mechanical load evenly across a broader surface area, ensuring uniform clamping force on the engine cylinder head.
High-Tensile Strength Composition: Forged from high-grade, heat-treated structural alloy steel to resist thermal expansion and stress stretching under extreme engine temperatures.
Anti-Corrosive Bright Zinc Plating: Coated with a premium protective layer to withstand moisture, road grime, and harsh weather conditions without oxidizing or rusting.
Direct Factory Drop-In Fit: Manufactured to the absolute exact dimensions of your original equipment factory fasteners for hassle-free thread engagement.
Maintaining a perfect, pressure-tight seal on your twin-cylinder engine head is crucial to preventing performance-killing oil seepage. During routine valve clearance adjustments, the engine's top-end fasteners are subjected to repeated removal, torque tensioning, and high thermal stress. If a factory screw stretches, degrades, or snaps due to over-torqueing, it immediately compromises the cylinder head seal.
The Genuine Royal Enfield Rocker Cover Bolt (SKU: 575248-D / Part No. 575248/D) is an OEM-spec, heavy-duty shoulder flange bolt engineered specifically for the 650 Twin platform. It features a unique unthreaded collar profile designed to seat perfectly into the rocker cover rubber gaskets, providing uniform clamping pressure across the top profile without crushing the seals. Replacing worn or stretched top-end hardware with this original component ensures a reliable oil-tight assembly.
