Nucleus bolt handle

So I must of loc-tited the knob on before, because he threaded stud is left.
I have the new Area419 knob.
Can I just clamp the handle in a vice and grab a vice-grip onto the stud to remove?
And, if so, how to clean up internal bolt threads of residual loc-tite (blue)?

Had the same issue with mine. An Area 419 knob will work. You just have to remove the set screw that serves as a stud once you get it.

I may still have my original knob minus stud if you want it.
