I would have used through bolts; here in the UK we call them coach bolts or carriage bolts. They have a squared end at the head end that will embed itself in the timber and allow a nut to be tightened without the bolts moving. Drill right through cross piece and rafter so you can push the bolts through and secure with a nut. Two bolts at each end will stop any rotation. This is what I did on my roof.
