My kitchen sink has four sink clips (a.k.a. mounting screws). If the edge on
which the faucet is located is "north," then the east and west edges have
two clips each, for a total of four clips.

Does anyone have more clips and/or clips located on all edges?

My disposer is causing vibration of the faucet and probably drain pipes.
The sink is probably 18 gage (the thinnest skin available), but I want to
see if more clips or better locations of the clips might improve the
situation.
