Knurled Aluminum Potentiometer Knob for Audio and Ovens
This is a knurled metal potentiometer knob designed so one family of designs can serve audio equipment, oven and gas appliance controls. It is CNC turned from aluminum, brass or carbon steel, with bores sized for pot shafts or valve stems and a laser-marked scale. Orders start from one piece, which suits brands needing matching knobs across product lines.

Manufacturing
How we make this part
Process, material options and inspection for knurled aluminum potentiometer knob for audio and ovens.
Using a common knob design across audio and appliance products saves design time but requires adapting the bore. We keep the outer profile identical and change only the bore and insert: a knurled or set-screw bore for audio potentiometers, a D-bore or spring clip for appliance valve stems. The knurl, top chamfer and indicator are turned and engraved in the same way across the range.
Aluminum is light and anodizes in any color, which suits audio gear. For appliance knobs near heat, aluminum still conducts warmth, so a heat-isolating insert or a brass body with a thicker wall can help. Carbon steel knobs are chrome or nickel plated for durability and cleaning. Laser engraving survives cleaning chemicals better than printed markings.
Bore fit is tested on each target shaft type, scales are checked for alignment and legibility, and the knurl is inspected for uniformity. Critical dimensions are verified on every knob before packing. Typical uses include audio amplifiers and preamps, kitchen ovens, gas cooktops, coffee machines, heaters and lab equipment controls.
FAQ
Frequently asked questions
Can the same knob design fit both audio pots and oven valves?
Yes, by keeping the outer shape identical and changing the bore or insert. Audio pots usually use 6 mm or split knurled shafts, while oven valves often use D-shaped stems. We machine each variant from the same program with a different bore operation.
Which knob material works best near oven heat?
Plated brass or carbon steel with a heat-isolating insert generally performs best near heat, as they keep their appearance and the insert limits heat transfer. Aluminum is acceptable when the knob is away from hot surfaces, and it offers lighter weight and more colors.
How do I get a quote for knurled aluminum potentiometer knob for audio and ovens?
Send a 3D model (STEP or IGES) and a 2D drawing with tolerances, material, finish and quantity through the quote form or by email. An engineer replies within 24 hours on business days with price, lead time and any DFM suggestions.
