Google "hex standoff" or "hex spacer" . Problem is most are too small
Get a metrical hex-nut, and bolt/stem with respective thread and a second nut. As grip use a grip from wood or plastic intended for files.
However as I once refrained from buying that head, but only bought the respective tripod, I forgot how that stem was fixed: just by that nut or in addition by a wedge inside that hole, so that after loosening that knob a bent stem also could be easily twisted around the stem axis.
Mshchem, what is a "hex standoff"? To my mind comes a hex-bolt with a thread, used to mount plates at a distance. Yes, off the rack these are too short and likely to small in diameter. But unthreaded hex-bolts are available (for turning nuts).
Also I do not think a hex-stem was used here. But that the hole has a hex-opening at both side makes no real sense to me, unless actually a hex-stem was used. Which then blocks any twisting, but only facilitates pushing-in/out that stem.
At Linhof catalogs I only see round stems at their various heads!

I have purchased an old Linhof Patentkopf III De Luxe Professional Pan Head III 003695 (Maybe 003614) or (003670) the sticker is very degraded, below the item/model number are two words - two lines - the first line word ends with (ielst). The tripod head needs a stem handle and insertion part to connect within the six-sided hole receptacle. Any suggestions? The double-sided toothed clamp disengages and tightens fully with the knob. The outer metal six-sided hole is a 7/16 inch or 1.11125 cm wall thickness of the metal that revolves around a solid piece of metal that has a matching six-sided hole through the opening completely through both sides. The opening measuring from parallel sides is 32/64 inch on the four parallel side widths - 1.27 cm, and 35/64 inch - 1.389063 cm on the longer measurement length opposite side two parallel angles in the hole. The match-up of the inner and outer metal hole shift off-axis from each other until manipulating a line up of the six sided hole on both outer and inner. The tripod head weighs 3 1/2 to 4 pounds - 1.587573 kg to 1.814369 kg. The whole outer sideways measurement parameter straight line through the depth of the metal-toothed column is 1 inch 11/16 - 4.28625 cm. I have a Kardan Color Triplex 8x10 with an extra extended monorail and extended bellows probably around 1964 / 1965 model, as well as a prototype first edition with the turn knuckles of a second Linhof Kardan Color Triplex 8x10 with an extended long monorail and bellows arriving in a few weeks. Is this head sufficient for the weight of a Kardan Color Triplex extended monorail with larger lenses on a Linhof Professional R Doppel Rohr Stativ 003323 mit Kurbelsäule Heavy Duty Pro 3, or possibly sufficient to carry the weight of a Linhof Kardan Bi 5x7 with extended long monorail with larger lenses? - These are pretty weighty items, especially with larger lenses added. So this Linhof tripod head seemed a good match???., - Thanks - Brad

Yes, AgX, Recently I saw a picture of this head in a brochure that had a single page on two Linhof tripods, with the other page on the newly released Linhof Kardan Bi System. The stem was quite long and had a 30% or so bend. Actually looking again at the brochure online - it's not the same Linhof head.

Thank you for the link!, mshchem
A beautiful head. I would consider finding a machinist.

Thread moved to the Large Format Cameras and Accessories sub-forum.
But what use would such thing have in this case?
-) basically*
-) by standard, as a german hex-hole is metrical
*Typically such lever mounting on its most basic form is a hole, with at one end a hex-recess. The stem of the lever has a respective thread and a arrest (wich can be mimicked by a nut up its thread). A nut is placed in the recess and the stem inserted from the other side, then screwed into the nut by force. Alternatively the stem screwed in is kept still twistable and then locked by such button as seen.
A coupling nut might work well, it would give you a female threaded hole to accept a handle.

McMaster also has similar thread adapting nuts that have two different threaded holes.

Thank you all for your input and information - very helpfull!
What need is there in this case for a coupling nut and a 2-threads nut?
What am I overlooking?
