Fasteners size for drive shafts

[e635815]

There are 6 BTR fasteners on each side of the drive shafts going from the dif. to the hub.
These fasteners are neither metric, nor UNF. I suspect they must be 3/8'' BSF.
Can someone confirm and also tell me where can I buy online?
Thanks for your help.

Similarily, the four BTR bolts holding the diff to its brackets. They must be 7/16'' UNC or BSW, right?

OTOMH drive shafts could be M8?

Mounts should be 7/16" UNC IIRC.

Drive shafts bolts are definitely not metric! On both sides...(I have checked with metric fasteners)
They look like 3/8'' but have 20 TPI, hence BSF, I think.

M8 is @ 3/8" & 20 threads per inch........

Nop....
M8 is 8mm diameter and 17TPI.
3/8" is around 9,54mm diameter.

I have tried with a metric bolts and it doesn't screw in. I know that on some cars, there are two different types of fasteners used wether you're on the diff side or on the hub side. On my car, they are both from the same type i.e. non-metric, around 3/8" diameter and 20TPI.
So BSW or not BSW?

I just trawled the net to see if I could get any cheaper from a fittings supplier. I could not beat Clever Trev's price, although I could match it. The other thing to watch out for is the tensile rating which should be 12.9 and printed on the bolt head.

M10 X 1,25 they are.....

Not easy, nor cheap to source!!

I bought a box of 100 bolts with washers for about £35 from a local engineering shop.
