Simpson has a line of screws specifically tested with their hangers and made for PT wood. I ould use those. Not all screws have a structural rating or are rated to be used with simpson or usp hangers. Blocking is required for some spans and will stiffen your deck and it is very inexpensive if you are providing the labor. I would suggest overblocking ie if required at mid point, provide at third points.

Great great info everyone! I appreciate it.

- I have a permit pulled and we ve had utilities marked
- We will be using joist hangers per code – what screws do you recommend for the joist hangers?
- I plan to flash with the membrane and coated flashing as a double layer
- I need to add blocking for the joists
- I also need to add blocking for the picture frame as well

I love the critical connections video I have watched them a few times already!

GRK RSS 5/16” x 5 1/8” for my ledge connection is what I was planning on, spaced at 6”
