that's a shame they're no longer being carried considering they were the goto for ccc bali upgrades.
i just checked all the pivots i bought from kk and none of them save one were threaded all the way to the base. so to make them work you'd have to cut both the pivot as well as the screw. there's enough threads in the pivot once cut to length (approx 3-4 lines) to be secure but not enough to be tightened if that makes any sense. well unless you're willing to use the screw as a tap or never take it out ever again that is.
maybe they're supposed to be threaded all the way? i'll send them an email to confirm. otherwise there's no way to tighten them at all even if a handle were to fit flush with the pivot
pic of the pivot and screws handtight. none of the screws sit flush except one which is not in the pic
