Best way to secure soffit 2x4 crossmembers?

Whats the best way to secure the 2x4 crossmembers?

I dont like the idea of toe nailing the 2x4s so I was thinking of either buying 5" screws or nails and driving them through the outside of the soffit straight into the 2x4 crossmembers.

I was also thinking I could use some kind of joist hanger system to secure the 2x4s. I feel both will give better support than toe nailing and prevent any future sagging.

How about using a pocket hole jig? You could also install some 1/2" steel track (used for steel stud walls) and attach your 2x to that.

Driving a screw through 3-1/2" side is too much work.

Toenail with 8d nails or the pocket hole screws (they're great for anything).
Attach a 2 x 4 at an L above each cross brace or every other cross brace.
Top 2 x 4 L can also extend over sides, helping to prevent sagging.
You should be OK.

Thanks, I guess I will just go to harbor freight and pick up a pocket hole jig. I plan on doing some built ins anyway so it will come in handy.

As for the L I love that idea unfortunately I don't have enough space for a 2x4 to fit that way. I will most likely try to hang some strips of wood from the joist in between the duct work for center supports unless someone has a better idea?

Yes,
Hang some strips. I didn't realize the soffit was that shallow.
That's easier anyway. The bottom looks about 48" wide, you shouldn't have any or much sagging.
Install cross members crown side up if you feel it will help. I'd hate to do that and then it doesn't sag.

Good guess, the crossmembers are actually 38" cuts
