Finally, the shape and look of the nut can vary widely. Most coupling nuts are hex shaped on the outside so that a wrench can be used, and most are open in the center on the top and bottom to allow a rod to thread through the nut. A cap nut is different in that the top of the nut has a dome over the opening.This is used for the end of a coupling rod. An acorn nut is similar to a cap nut, but the dome is shaped more like a cone instead of a dome.n additional type of coupling nut contains something called a sight hole. This is a hole in the outside of the nut which travels all the way through the material.
