only a matter of time before the vibration makes it get all slack
it is a big thread and has quiet a bit of free play movement a lock nut will keep the thread preloaded and frim
you can always cut down a full nut to a half nut if none are availble
(a full nut may even fit if there is room)
You are quite right they did check at my iva
Full nuts fit too, well on mine they do anyway!
