BSF / BSC
Click an underlined link below to jump to that list
A lot of the early threads,i.e. BSF, BSW and BSC are no longer manufactured
by the larger companies, so we have to have some of these made. Depending on quantity we can get them forged or bar turned. We usually keep good stocks of these threads. For the later threads, UNF + UNC, some of these are hard to get in high tensile and stainless so the same applies.
If there is something you want to know or your not sure about, something you cant find, or if you just need advice, please email or phone me, if I can't help I might be able to point you in the right direction.

BSF/BSC (Cycle) and BSW (Whitworth) fit most British motorcycles that were made up to the 1960s. During the 1960s all manufacturers started to change over to UNF/UNC. During the 1970s/early 1980s this then changed to metric to include metric fine as well as coarse
The American motorcycles  Harleys, Indians, used UNF/UNC from the beginning.
Please remember that we do have lots of items not listed in all threads and sizes, so ask.!
Washers
Most sizes of washers are available in £1 bags, this includes standard washers thick washers, spring washers and some penny washers. This works out cheaper for buying washers, especially if you require more than 10.
