Most of the fasteners that common british cars used we "BSF" ( British
Standard Fine". This is so close to our own National Fine, that the fasteners
are interchangeable. The thread pitches, and major and minor diameters are the
same. "Whitworth" mostly shows up on subsystems that the OEMs bought from some
other maker, like hydraulics or carburetors.
"BSP" stands for "British Standard Pipe". This rarity shows up in a few
hydraulic fittings. I believe that the master-cylinder-to-reservoir pipe on my
TR3 master cylinder used it.
