Keel bolt supplier

[nct1]

I am after a couple of mild steel 35mm head (but will be imperial equivalent) keel bolts.

Does anyone know where I could buy them, it's for a Sigma if that makes any difference.

Yes I do know some Sigmas originally had studs with nuts, but mine has bolts.

Any good industrial fastner supplier should be able to supply what you need.

A supplier will need to know the diameter of the thread, not the hexagon size. A 35mm head, (1 3/8 inch ). will probably equate to a 7/8 inch thread diameter. An an imperial size, especially BSW and BSF, won't be too readily available unless you are lucky. Industrially and commercially, these two have been non-preferred standards for several decades. An internet search might throw up a supplier.
As a last resort, a machine shop could make some for a price.
Good luck in your search.

Thanks for the responses, the information was useful.

If anyone has had dealings with a particular company that has supplied keel bolts, any recommendations gratefully received.
