I have been putting in a cut roof ..... where the joist crosses the
rafter I have arranged that these meet side by side rather than meeting
under each other (as in a truss)
What is considered best way of joining these together ...
they are 100 x 50 treated C24 timber.

i.e. as per this sketch ...

I could simply screw together with 2 coach screws per joint, using

This would seem strong enough to me, these are the fixing that are used
to join joists together to make double joists .. have a load left over
from a truss roof job.

I could even put a timber connectors between them as well

Or to use those would I need to put a thru bolt

and have this pass thru the timber connector ...... just the thru bolts
will not look nice as open rafters on show.

In most traditional roof jobs, a couple of 4" nails!

Yup, that would work as well. The SF style turbo gold ones might look
better if on show.

Normally used with bolted connections... if you predrill one side prior
to using the coach screw you might get enough clamping force to make
them worthwhile.
