Ensure precise valve adjustment and reliable engine performance with this OEM Adjusting Screw Hex Nut, designed for TD5 engines in Land Rover vehicles. Small but essential, this hex nut secures the adjusting screw within the rocker arm assembly, helping maintain correct valve clearances for smooth, efficient engine operation.
