EQ6-R Main Mounting Bolt Thread Size/Pitch

[Spaced Out]

Hi All

I'm just working out how to mount an EQ6-R onto my existing concrete/brake disk pier. I had hoped that the main mounting bolt (the one that goes through the centre of the tripod underneath and up into the base of the mount) would be the same as my old HEQ5 but it seems a bit larger. Can anyone tell me the thread size of this bolt and the pitch so I can order one to fit ?

Thanks

A quick search came up with this post where the same sort of question was asked for an EQ6 - Seems its  an M12mm x 1.75mm pitch.  Further google stated on another forum that the EQ6-R was the same M12 thread

That's great thanks. New bolt ordered !

Sorry I'm late for this, but I believe this bolt has two different threads and certainly a recessed shoulder along roughly the middle of its length. This is not at all a standard bolt, but one could hack one with some washers and bolts and make it work. The two different threads are to accommodate the 'rose bud' tightening knob on one end and the actual mating thread for the mount head, on the other end. Where the two threads meet on the bolt, about 1 cm of thread has been removed, such that it can be left in place without falling out when it is not screwed into the mount head.
