Not sure what you are fastening, but those nuts with a rounded crown appear to be non-standard. Is there blue epoxy coating on some of the threads? This is a common joint thread locking feature. Or, do you see white plastic around the top of the nut? This also is another way to prevent the joint from becoming loose. Let me know as I am a fastener engineer from Ford. These concepts are used when only a shallow height nut is necessary, because over torque-ing will break the nut, not the bolt or stud which is the desired failure mode. You need to know the torque spec. for correct installation.I gotta tell you, that looks crossed or probably not enough threads. I'd go to the Ford dealer and get the nuts they use, those you're using do not look very supportive.
