We've been trying to come up with some appropriate comments for these knobs, but... there are none. These things speak volumes for themselves! Like all Q-Parts knobs, they come complete with a removable insert that allows you to use them on either metric, US, or solid shaft pots. All Q-Parts knobs utilize a set screw to insure a tight, non-wobbly fit.
