the tool handle for a bicycle fork threading die, is a special one .

.. there is another Sheldon trick use a 1" threadless headset and spacers and the top lock nut on the threads

better.. if you can get a 2nd through-threaded nut to use a Paired jam-nut scheme.



I did a threading extension, before the threadless headset was a thing.. if I were to do it again that combination scheme is what I'd Do..


Cannondale shipped a cable hanger that had a thin 32mm nut and a pinch bolt piece ,with the bikes.
shop assemblies often used regular headset parts

so a bin of these nuts filled up .. I found them very useful in my touring bike build ,, where I had a tall fork steerer for stem height.
