hex / Allen wrench for Tayda chicken head knob

[davepedals]

Hi, does anyone know what size hex / Allen wrench I need for Tayda chicken head knob?
I had 2 and of course lost them, so darn tiny!  No one locally has them that small. Tayda not Answering me.  Thank you.

I can't remember the last time a saw allen keys sold individually, a metric set that includes 'tiny' should cover it.

edit. My metric set starts with 1.5mm, 2, 2.5...

Despite having a set of small sized allen wrench, I have a very small screwdriver that perfectly fits the small screws I (very rarely) have to set. You can get a piece of hard metal wire (a spoke from a bike wheel does the job nicely), hit one tip with a hammer to flat it, then ajust it to the size needed.

The brass is pretty soft and easy to strip out. Ask me how I know.
