What do you mean, sideways? Do you mean downwards? Or into the wall, opposite of outwards? Why would they be rated for sideways force? How and when would sideways force be applied? Literally cannot figure out what it means in the context.

Sideways as in in the plane of the wall. Up, down, left, right, or any angle in between those. Usually the load is down because well, gravity. Just not in toward the wall or out away from the wall.

So you meant lateral? Why not say that? You've broken like three conventions at once, it's very confusing.

Because a bunch of laypeople may not know what lateral means, and I'm trying to make the information as accessible as possible. That's also why I explained shear and tension.

But also because lateral is no more accurate or precise than sideways. Lateral loads are horizontal, as made distinct from vertical loads. The most correct terms are shear and tension loads, or possibly in-plane and out-of plane loads.
