Help with a Tightening Knob question
I bought a beauty dish with a flash attachment and the base tightening knob broke. It's a tight set of screw threads measured to what seems like 3/16th.
I took a base tightening knob off an umbrella stand and used it in the beauty dish so I'm assuming this is a common size thread.
Well I've tried twice now to order a replacement on Amazon and both were too big so I'm doing something wrong.
So, Q is what size is this (seemingly standard) tightening knob and does anyone know where to buy more?
