Set **** is missing from  my Flex Control knob. Anyone know the size set **** I need? I'm also looking for an easy route to get one. Can I purchase one from Flex or does some nice "Flexer" have an extra they will sell.
Thanks fer your time.

    I mic'ed it at 0.110" diameter and 0.375" long. That looks like a common #4-40 setscrew in stainless steel. The tip was conical shaped but since the shaft has a large flat I would expect any easily available tip form to work.
    Suggest you check the local hardware store for a replacement.

    Best Regards,

    PS: A 0.050" allen head is required.

    If you don't have measuring gear, you could take the knob to your hardware store for a trial fit.  K3TIM is likely spot on, but it could save a return trip by double checking the fit right at the store.

    Must be a back-story how the **** came to be lost?
