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 Aluminum Machined Knob in Blue Steel.

It's a solid machined aluminum 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 color

This knob has a set screw that uses a 2mm hex wrench (not included) which means it can be used with either T18 or D-shaft but it does not fit on round potentiometer shafts that are 6.3mm diameter ! Please use calipers or datasheets to verify that your target pot/encoder has 6mm or smaller shaft.

To use, simply loosen the set screw, press onto the shaft, and tighten the set screw so it no longer rotates.
