Geo. To be more specific, I meant the grasping knob which fits around the center mounting bolt. This bolt comes up through the center of the tripod and secures the equatorial mount to it. It looks like a tooth gear with 4 projections or teeth for grasping. Apparently the bolt head was press fitted into this plastic knob to make it easier to spin without using a wrench. Sorry if I'm making this more confusing. With what was left in the accessory tray, it must have looked like the one in the Celestron link above. The now revealed bolt head is definitely 9/16th. Hope this helps.
Thanks Everyone !

But imagine this bolt with that 4 tooth plastic handle pressed over the bolt head and you have it. Any ideas??
And should this bolt be smooth in the middle as it is. I purchased this mount and tripod second hand so I do not have any manuals.

The threads are filed down in the center to allow screwing thru a tapped hole then attaching to another thread above that while the body of the filed down screw passed through the first threaded hole without binding.

Skywolf, yes, where it passed through the tripod top plate is threaded along with that silvery part on the equatorial mount. So you think it should be smooth in the middle for snugging up?

I agree with Skywolf 856, it looks like a homemade bolt for the purpose. That's just fine. Yes, it is normal for the middle part to be smooth. It allows you to push it up to the mount base and then start threading/tightening it. I'm assuming that there is a washer or spacer of some sort for the bolt near the head end.
