The locking screws are 4mm, and the locking rings are made of aluminum alloy. Applying too much force may cause the screws or locking rings to slip. Pay attention to the tightness of the locking ring when tightening the screws. If the grip can still rotate after tightening, do not over-tighten, as further tightening may cause the threads to slip.
