I am installing an Insinkerator Evolution garbage disposal on a Vigo farmhouse sink. I used the 1 1/2" screws provided, but I realized later that the instructions say to use 1 1/8" screws for sinks larger than 3/8". I believe this applies to mine, but I’m not positive. I already have the flange in place, so it’s hard to tell (I did have to buy the extended flange). I wasn’t sure of the reasoning for the shorter screws. Should I swap them out, or are they okay as is? I seem to have a tight connection. Thanks.
