Wood – How to fasten wet dog-ear pine pickets

fencescrewswood

I got some fence pickets for a small, outdoor project (a garden box, something like this).

They are super wet (I literally get sprayed when cutting on a tablesaw!) and SUPER soft – with a little wiggling I can pull a #8 screw right out of the board. The boards are only 5/8" thick, so when screwing two of these together a 1 1/4" countersunk screw pokes out the other side, so I'm only using 1" screws.

Is there some trick to fastening these so they won't pull apart? I'm planning to put a few bags of soil into this box and I'm afraid the weight will just rip all of the screws out.

As you suspect, pressure-treated lumber holds fasteners much better when it dries out somewhat. That would take some time, though, as you don't want to rush it or you'll get severe warping.

If you're in a hurry, switch to something like 1/4" carriage bolts. They don't depend on thread grab and will hold better in the long run anyway.

Otherwise go to a heavier screw. A #12 has several times the thread area and will hold much better.
