I am building a pergola where I have made a frame with 45x145 that is about 4 meters. Now I want to recess 45x120 joists between these with a 400 cc. I don't want the joists to sit on top as you often see.
I thought I would screw these from the outside with a couple of 6x100 screws in both ends. However, I'm unsure if it will hold or if the timber will be weaker when I screw into the end grain?
Attached is a small picture of what I am thinking.

Yes, it might be wise if I'm going to screw into end wood.
I'm starting to consider if I should notch out the studs instead.
It will be easier to screw down, but I'm not sure I like the look of a bunch of stubs from the studs sticking up. I don't want to lay the studs in the other direction either, as I think it would look worse.

Our balcony is constructed with 45x220 and is attached to the facade with a beam as you describe - with screws into the end grain - and I believe they used 3 screws in each beam. The dimension of the screws was probably 6x180 mm. Then the beams rest on a glulam beam about 2 m from the facade and are screwed in the same way into a finishing beam on the outer edge. The beams are set with c/c 600 mm and there are no issues with strength or deflection.
In a pergola, there isn't much load, so I definitely think two screws 6x140 at each end should be sufficient to hold your beams in place.
