Yeah I use them for the boards mate, but I am looking at screws for the sub frame.

I use these, more suitable for outdoor.

They more suitable for fixing inner joists?

I use them for fixing joists to posts and all subframe joints. Also for sleeper walls. Be aware you will need an impact driver though or a corded sds to get them in without pre drilling.

got myself a wee impact driver a few weeks ago so should do the trick.

Cheer buddy!
