Two high quality blue-anodized potentiometer knobs for use with amplifiers, preamps, guitars, radios and other devices that have 6.0 mm diameter potentiometer shafts. 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 blue 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 Amazon Storefront if you need a four-pack of this knob or the same knob for a larger ¼ inch diameter shaft.-----
