These compact and luxurious machined knobs look fantastic and have a nice feel, a perfect way to upgrade your rotary encoder or potentiometer. We hand-selected the best knobs for your project in different sizes and varieties. This is an Anodized Aluminium Machined Knob in classic Black. It's a solid machined aluminium knob, with knurling on the sides for grippyness, and a shiny anodized coating. It looks like the type of knob you'd find in a suped-up recording studio. There's a white triangle on the finish so you can know where you are and figure out where you're going. We have these in a few different colour. This knob has a set screw that uses a 2mm hex wrench (not included) which means it can be used with any 6mm shaft rotary encoder or potentiometer: T18, round, D-shaft! Simply loosen the set screw, press onto the shaft, and tighten the set screw so it no longer rotates. More colours are available in the store!
