With a diameter of 25mm and a height of 15mm, these knobs feature a vibrant blue anodized finish that enhances both aesthetics and functionality. Each knob is CNC machined and rigorously inspected to ensure top-notch quality, making them perfect for amplifiers and electric guitars. ## Description Two high quality blue-anodized potentiometer knobs for use with amplifiers, preamps, guitars, radios and other devices that have 1/4 inch diameter shafts. These great looking knobs are high quality and 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 blue anodized surface finish. Dimensions: 25 mm diameter, 15.5 mm height, 1/4 inch shaft hole diameter. *****PLEASE NOTE: These knobs will only fit potentiometers with a nominal 1/4 inch 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). PLEASE...Accurately measure the potentiometer shaft diameter and it's length with calipers or a micrometer before placing an order - that small 0.4 mm difference in diameter between European/Asian (6.0 mm) and US manufactured (0.25 inch / 6.35 mm) 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 identical knobs that fit European/Asian 6.0 mm diameter potentiometer shafts. ## Features - Two high-quality anodized potentiometer knobs - solid aluminum - CNC machined. Fit 0.25 inch shaft diameter. Blue anodized surface finish. - 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 0.25 inch (6.35 mm) diameter shafts. - Will fit potentiometers with 1/4 inch (6.35 mm) shaft diameter. For similar knobs compatible with 6 mm diameter shafts please visit our desertcart Storefront. - **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, Blue) Potentiometer Knobs. for 1/4 inch Dia.

The shipping box was excellent, with individual foam cutouts providing good protection for the two knobs inside. An added bonus was a 2mm Allen wrench, needed to tighten the set screws. I would like to see these offered in black and silver anodized finishes as well. ### ⭐⭐⭐⭐⭐ Fits 1/4 in. Shaft *by G***T on Reviewed in the United States πŸ‡ΊπŸ‡Έ on May 28, 2018* Good quality knob.
