Joining plywood at 90 degrees: Pocket hole or just screw into the end grain
I will assemble 18mm plywood boards to create the frame of a piece of furniture.
When I assemble the frames, they will give me a 90-degree angle.
How do I assemble this in the best way? (I don't have brads) I won't see the holes at all. So we're only talking about time and strength here đ
1. Pocket Hole jig. Drill and screw together

2. Pre-drill and screw through the board into the end grain of the plywood

3. Drill through the board and into the end grain and plug with wooden dowels

Wooden dowels are probably the best, if they won't be visible you could also consider a wooden block or metal brackets to screw into.
Screwing into the end grain of plywood is usually not a good idea, but if the plywood is as thick as in the picture maybe it will work.

If it can be done without being visible, the pioneer's tip of using a piece of wood on the inside of the angle is cheap and good. Glue and screw it for real strength without any special tools.
Thank you for the response.
Pocket hole would be visible
Kloss would be visible, and also take up some space, as well as complicate the shape of the shelf
Angle iron would be visible
Of the above, a pocket hole would look the nicest... but maybe also the hardest to get perfect

Use dowels and glue, so you avoid anything visible.
Buy a kit like this https://www.hornbach.se/p/wolfcraft-startset-for-pluggborrning/4061460/ if you don't already have one, but make sure you can clamp it properly during the drying time.

Perhaps it was silly to ask, because I went with pocket hole in the end even though no one recommended it here.
Turned out insanely good and stable, far exceeding expectations and probably much more stable than end screw or plug could ever be. RECOMMENDED!
