Screws vs Nails

I am trying to figure out what is the correct way of using screws and nails in the construction of my deck.

My deck is going to be constructed in this matter:

1) Beam on top of post, beam fastened to post by diagonal screws. Should I use post connectors instead with nails?

2) Joist on top of beam, using hurricane ties fastened by nails to connect to the beam. Should I use diagonal screws instead?

3) Deck boards on top of joists - screws

Thanks.

Connectors should always be used if the beam fully sits on top. If the post is notched it should be bolted. (Posts should be 6x6, not 4x4.)

ties and nails or Simpson screws, yes.

yes.

composite decking has to be screwed not nailed. wood you can nail but screws hold better but nailgun is fast. dewalt dw257 deckign gun is amazing and pretty fast though in the right hands (and can do drywall with cone but gets heavy and not as zippy for drywall needs but works ok

yes use decking bracket hardware for post-to-beam connection. and bracing especially if required there.


hurricane ties on joists: just nail them with the 10D nails hot dipped galvanized sold right near the hurricane ties, make sure head says 10D on it (thicker ones) if being inspected.

nails are usually much much stronger than screws. you can bend a nail much easier. but screws are good for preventing stuff from pulling out but don't use screws for anything where the screw is holding weight . they make screws now as strong as nails in the same or slightly thicker diameter but might be cheaper and easier to just use nails, plus pressure treated wood is usually wet and takes nails without splitting so no need to want to use screws and predrilling.
