Want to build a vertical timber screen at home (merbau 42 x 19’s) Plan was to screw the battens to the joists. However, interested to know if the joists should be screwed or nailed to the posts?
Interested in thought & opinions. Thanks
Personally... I'd be going for screws. Neater finish, less chance of bruised timber.
Even if nailing you'd likely want to be pre-drilling & slightly countersinking with merbau too as the risk of spliting is high especially on the ends.
I used one of these a while back when I put up a slatted screen & found it seriously useful
I'd be going for an M10 coach screw and recess the head into the joist, or a cuphead bolt, that way as timber shrinks and ages you can tighten it up again. I have been known to over engineer things though.
