These great looking knobs are precision machined from an aluminum alloy. The knobs have a knurled finish around their circumference. These knobs do not have a plastic insert; they are CNC machined from one piece of solid aluminum, with a durable black anodized surface finish. Dimensions: 25 mm diameter, 15.5 mm height, 6.0 mm shaft hole diameter. *****PLEASE NOTE: These knobs will only fit European/Asian manufactured potentiometers that have a nominal 6.0 mm shaft diameter.***** The shaft hole depth is 14 mm (this depth includes the 10.5 mm drilled depth and a 3.5 mm machined recess on the backside of knob – see photos). NOTE...Sorry but these knobs WILL NOT FIT ¼ inch (6.35 mm) diameter potentiometer shaft. Please...accurately measure the potentiometer shaft diameter and length with calipers or a micrometer before placing an order. These knobs are solid aluminum and will not fit a 1/4 inch shaft - that small 0.35 mm difference in diameter between European/Asian and US manufactured potentiometer shafts is very unforgiving when it comes to metal knobs! Each knob is secured to the shaft with a single setscrew (setscrews and a 2 mm hex wrench are included with the knobs). *****Please visit our Storefront for larger quantities (4 knobs) or the identical knobs in red, blue or gold color.***** ## Features - About this item - Two high-quality anodized potentiometer knobs - solid aluminum - CNC machined. Fit 6 mm shaft diameter. BLACK anodized surface finish. Please visit our Storefront for larger quantities (4 knobs per box) or the identical knobs in red, blue or gold color. - We are perfectionists when it comes to audio products. All knobs sold by Riverstone Audio are meticulously inspected to ensure they are free of scratches and surface defects and packed in foam-lined boxes to prevent damage during shipping. - 25 mm diameter x 15.5 mm height - drilled for 6 mm shaft diameter. - Will fit potentiometers with 6.0 mm shaft diameter - not suitable for use with 1/4 inch (6.35 mm) diameter shafts. - **Please Note: The color of anodized surfaces can vary slightly with different light sources (LED, CFL, incandescent or natural light) and viewing angle. The pictures of the knobs were taken in natural light. For an artificial light source, the color may vary with the CRI (color rendering index) of the light source. The interaction of quality anodized surfaces with light source and viewing angle is one of the beauties of anodized surfaces and why our knobs are anodized, not painted.** ## Images ![Riverstone Audio - Pair (2 PCS, Black) Potentiometer Knobs - for 6 mm Dia.
