5/16 Center Locking Lock Nuts
Two-Way Reversible Lock Nuts, also known as Centerlock Nuts, get their name because of their functionality and their ability to be used either top-up, or top-down (reversible). Two Way Lock Nuts feature indentations on the outside flats of the nut, which distort the internal threads to increase resistance against the mating part.
