Most commonly used for fuel gas fittings, or in situations where a right hand thread would tend to undo.
Have you tried them on a bolt?

A two-way reversible lock nut is a hex nut with two or three, round or rectangular indentations, compressed onto the flat sides of the nut equal distances from each other. The compressions create slightly distorted center threads resulting in a controlled locking action when the threads of the mating part become engaged. The two-way reversible lock nut is designed for use with machine screws and low-carbon bolts, and allows for automatic assembly because the top and bottom of the locking nut are the same. The nut will create a locking action even without being fully threaded onto its mating screw. Two-way reversible lock nuts will withstand higher temperatures than nylon insert lock nuts (nyloc nuts).

I'm sure nyloc nuts are fine .. not suggesting otherwise, I was just trying to identify what the markings on my originals mean and I think a reversible locknut is a likely explanation. The 6 securing the carbs have been on and off a good few times over the years and there's not much "locking" left ... I should probably replace them ... but they have never come loose yet. Do you also have nylocs holding the adaptor blocks to the head .. is the recess deep enough?
Cheers.
