Heavy-Duty Steel Control Knob with Coloured Cap

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.
