This M8 hexagonal nut is used to secure exhaust system components, with specific application to manifold-to-cylinder-head fastening on applicable engines. Exhaust fasteners operate under sustained high temperatures and are prone to corrosion, seizing, and thread degradation over time. Using the correct replacement nut ensures proper torque retention and a reliable exhaust seal, preventing gas leaks at critical joints. Key Features M8 thread specification for precise fitment to exhaust system mounting points Hexagonal head design compatible with standard spanners and sockets for straightforward installation Supplied to OEM specification for the Freelander 1 and Range Rover P38 exhaust systems Exhaust nuts should be replaced as a set during manifold removal - inspect studs for corrosion or thread damage at the same time Vehicle Fitment This nut fits the Freelander 1 Td4 2.0 Diesel exhaust system and the Range Rover (1995–2002) 2.5L 6-cylinder BMW Turbo Diesel, specifically at the manifold-to-cylinder-head joint.
