Riverstone Audio - Pair (2 PCS, Red) Potentiometer Knobs - For 6 mm Diameter Shaft - Solid Aluminum- 25mm dia.x15mm height, Volume Control Knob, Amplifier, Electric Guitar, Finish RED, 6 mm shaft

Two RED color anodized potentiometer knobs for use with amplifiers, preamps, guitars, radios and other devices that have 6.0 mm diameter potentiometer shafts. The 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 red-color 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 with 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 shafts. 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 most 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). *****If you are interested in similar knobs with different color (blue, gold and black) or for larger quantities (4 knobs), please click on "Riverstone Audio" at the top of this page to view additional choices.*****
