Product Description
RTC3629 is a 5/16th UNF hexagon nut used in the exhaust system of Land Rover Series vehicles. These nuts secure exhaust manifold flanges, downpipe joints, and related connections where high-temperature cycling causes fasteners to corrode, seize, or strip over time. Using the correct thread specification is essential to ensure a gas-tight joint and prevent exhaust leaks at manifold or pipe connections.
Key Features
- 5/16th UNF (Unified National Fine) thread form - finer pitch than UNC, providing improved clamping retention in exhaust applications
- Hexagon head profile for standard spanner or socket installation
- Matches original Land Rover exhaust fastener specification for Series 1, 2, 2A, and 3 models
- Exhaust fasteners should be inspected whenever the exhaust system is disturbed; consider replacing in sets to ensure uniform clamping across all joints
Vehicle Fitment
Fits Land Rover Series 1, Series 2, Series 2A, and Series 3 vehicles across all variants equipped with 5/16th UNF exhaust system fasteners.
