I remember seeing an aftermarket cartridge bb that had 6 pin-holes and no lockrings.
I had to presume that they supplied a 6-pin tool for tightening it to a reasonable torque level, but seemed kluge-y to me. Maybe the pin holes were on the fat side, I can't recall.
I use the Park pin tool with a hinge, so it's adjustable, and can provide enough torque even for assisting the lockring's tightening, as the cup also rotates into it's very final state of adjustment. This has always seemed to give the most robust adjustment, as opposed to putting all foreward torque on the lockring tool while holding the cup stationary.
