This is a set of two top hat-style knobs with a nice shiny gold finish over a metal body. These are intended for use on potentiometers with 6mm shafts, and include a set screw for firm mounitng. A beautiful abalone top piece completes the look and feel of these knobs, putting them a step above their cheapers plastic press-fit cousins. These knobs will add a very classy, distinctive look to any guitar, amplifier, radio or other audio/electronics project.
See the photo with the ruler for sizing reference.
