Land Rover Part Number: BTR475 - Hex Nut - U-bolt
BTR475 is a hex nut used with U-bolts to secure U-bolt fixings on the sunroof control and headlining assemblies in Discovery 1 and Discovery 2 vehicles. Fitted where U-bolts retain the sunroof control unit and headlining components, this nut provides the clamping force required to keep the assemblies secure; inspect for corrosion or thread damage before refitting and replace if damaged.

Frequently Asked Questions
BTR475 secures the U-bolts that retain the sunroof control unit and headlining assemblies, preventing the U-bolt from loosening under vibration. Common issues are corrosion, thread wear or loosening; inspect the nut and threads and replace if damaged or corroded. Ensure threads are clean and correctly engaged to avoid cross-threading when refitting.
