What terminals to use for stacked boards

I'd like to stack a bunch of boards with terminal blocks on the edges of each of them. The boards are stacked with only 10mm of spacing in between them. With regular terminal blocks, the screw terminal is inaccessible once you stack the boards.

What's something that works like a terminal block except lets you adjust the tightness on the edge as well?

I was looking at Weidmueller but was wondering if there's a better solution out there?

The right angle terminal blocks will allows you to access your wiring, however, you may be pressed to find one compact enough to allow 10mm spacing. Might want to use digikey to run through specs on various manufacturers.

Do you specifically need screw terminals? We sometimes get caught up in a particular solution and lose sight of alternatives. Apologies if you have already dismissed this idea...
It would depend on the current the terminals need to carry - but could you use something as simple as 90-degree header pins as an alternative? Taking that thought a bit further, if you have the room for an extra board in the stack, would be to put all your screw terminal blocks onto a separate board which is stacked on top of all the others so that you have access to the screws, and then run jumpers from the edge accessible header pins on the lower boards up to the screw terminals on the top board?
Another option might be pcb mounted banana plug jacks, but as chopnhack said - the 10mm clearance might be a sticking point.
