This is a 1/4 inch BSF (British Standard Fine) bolt used across various fixing points on the Land Rover Series 3. BSF fasteners use a finer thread pitch than BSW (Whitworth) equivalents, making thread compatibility critical - substituting an incorrect thread standard risks stripping threads in aluminium or steel housings. Using the correct specification bolt ensures proper clamping torque and prevents fastener failure in service. Key Features 1/4 inch BSF thread form - finer pitch than BSW, not interchangeable with UNF or BSW bolts of the same diameter Suitable for use in metal housings and brackets where correct thread engagement is essential Matches original Land Rover Series 3 fastener specifications for fixing applications Inspect mating threaded holes for wear or damage before installation; replace in pairs or sets where applicable Vehicle Fitment This bolt is compatible with the Land Rover Series 3 across fixing applications requiring 1/4 inch BSF fasteners.
