Hamilton Trombone Stand Set Screw

[LeonardFalconeEnthusiast]

Hi everyone,

On a standard old-school Hamilton stand, there is a metal sleeve that goes over the upper rod, to adjust the height of the rubber resting-thingy. Mine was a tiny little hex screw, and after I unscrewed it, I dropped it, and haven't been able to find it. I need a new one. Does anyone know the exact size I need, so I don't have to bring my stand to the hardware store with me? Thanks for your help in advance.
