Large Plain Cylindrical Solid Aluminium HiFi Control Knob

Large Plain Cylindrical Solid Aluminium HiFi Control Knob

This substantial cylindrical control knob features a clean, minimalist design with a perfectly flat top surface and a subtle recessed dot position indicator. The knob's generous 30mm diameter provides excellent grip and control, whilst its solid aluminium construction ensures durability and a premium feel.

The knob's cylindrical profile creates a sleek, modern appearance that complements contemporary audio equipment and electronic devices. The recessed dot indicator sits flush with the top surface, providing clear position reference without disrupting the knob's smooth aesthetic. This design makes it particularly well-suited for high-end audio applications where both functionality and visual appeal are important.

Hole Type

Round Hole

A knob designed for a round shaft has a smooth, cylindrical hole that matches the shaft's shape. This type of hole allows the knob to slide easily onto the shaft, relying on a grub screw / set screw or friction to keep it in place. This design is widely used in audio equipment, consumer electronics, and control panels due to its simplicity and versatility

A knob with a round hole can typically also be used on a D type shaft in the 180° position (where the position indicator is opposite to the flat of the D) and can often also be mouned to splined shafts in low torque applications.
