Agree about replacing locknuts if there is any question. McMaster-Carr has the three common non insert all steel types. Castellated takes a cotter key, flex top has a smaller diameter thread in a segmented area which squeeze the bolt threads tightly as the segments are forced open by the bolt diameter and interference has malformed or distorted threads that because of the mismatch with the bolt threads becomes very tight on them. Flex top and interference locknuts are rated for high vibration use.
