Drill a hole and glue in a dowel, then drive your screw into that.

Make the dowel as large as you can.

Use confirmat screws, they’re designed for that purpose.
You’ll need to pre-drill for them, but they work well.
Hafele sells them.

the dowel works well for a tougher joint. I think the secret is to not overtighten it. Definately predrill and drive the screw by hand…..Trya screw with a big bite as well like a sheet rock screw or similar

Yes, the dowel idea sounds good. What about screwing into composition wood or particle board?

Drill a pilot hole and squirt in cyanoacrylate glue. It will provide a good grip.

I don’t know if GaryK was referring to drilling a hole into the edge and inserting a dowel or drilling from the side and inserting a dowel. For me, the best way, if the project allows it, is to drill through from the side insert the dowel, drill a pilot hole and screw into the side of the dowel rather than the end grain. Either way will work but you get a lot more strength inserting the dowel so that you aren’t screwing into the end grain of the dowel.

And be sure that you’re screwing perpendicular to the grain of the dowel too.

Yes, dowel from the side, how far in from the edge should it be? I imagine a half inch or more.

Have your say...
