Two red anodized potentiometer knobs for use with amplifiers, preamps, guitars, radios and other devices that have 1/4 inch (6.35 mm) 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 potentiometer shafts 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). NOTE...Sorry but these knobs WILL NOT fit 6 mm diameter potentiometer shafts. Please...Accurately measure the potentiometer shaft diameter and length with calipers or a micrometer before placing an order - 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). Color: RED. Please visit our Amazon Storefront for identical red or blue knobs that fit European/Asian 6.0 mm diameter potentiometer shafts.
