Compact Knurled Aluminium Control Knob
Compact Knurled Aluminium Control Knob
This compact control knob features a cylindrical aluminium body with precision knurling around its entire circumference, providing excellent grip and tactile feedback. The flat top surface incorporates a clear position indicator line that contrasts against the knob's finish, making it easy to see the current setting at a glance.
The knob's solid aluminium construction ensures durability whilst maintaining a professional appearance. Its compact 15mm diameter makes it ideal for applications where space is at a premium, such as audio equipment, test instruments, and control panels where multiple knobs need to be positioned close together without interference.

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.
