Two way lock nuts are low cost, one piece, all-metal prevailing torque hex lock nuts with chamfered (beveled) corners. The locking action is created by two or three equally spaced rectangular or round indentations centered in the flats (sides) of the nuts that slightly distort the threads. Two way lock nuts are considered "two way" because they can be installed either way, which reduces automated assembly costs (their tops and bottoms are the same like regular hex nuts).
