I find that the ADM Rosette Know Hand Tool works well for me:

A small strap-wrench would probably also work.  They have lots of leverage and the rubber/plastic parts don’t mar the aluminum.


But I’m confused.  All my AP knobs have a hex socket in the middle of the knob.  That said, all mine are at least 6 years old.  So maybe AP has recently changed to the solid knobs with no hex socket in the middle.  Too bad.  Although I’ve NEVER needed to tighten anything that tight.  But I can see perhaps needing the hex key to loosen a stuck or seized knob.

Hi Gert

Out of curiosity what is the part number of your dovetail plate ? The knobs look like those on my DOVE15 which has no hex head bolts in the clamping knobs either.

I have had pretty good luck using a jar lid gripper on these knobs. They are simple, cheap, and effective. You can find them in the kitchen section of most department stores (e.g. Wal-Mart). I have noticed something interesting about these grippers though. It seems that after a period of time they will lose their "grippiness" and you will have to replace it.
