As I was resetting my kitchen sink after undermount bolts came loose
I noticed a bolt (3/8) going thru the bottom of sink cabinet with a nut on it and it was threaded into something under the cabinet (it went thru cabinet floor, it did not hold cabinet as hole is larger than bolt and nut)
it looked like the bolt would tighten into a fitting and the nut on it would lock it in place
I have no idea
