Perfect fit for my audio project
The build quality is exceptional. The aluminum feels solid and the anodized finish matches my chassis perfectly. The 6mm hole fit my shafts without any wobble.

Good but limited color stock
The quality is good, but the blue color I wanted was out of stock. Had to settle for black. Product itself works as described though.

Exactly what I needed
Restoring vintage radios requires specific sizes. The 24mm option was hard to find elsewhere. Fits perfectly and looks authentic.

Great value, minor shipping delay
The knobs themselves are fantastic for the price. Very sturdy and look professional. Only giving 4 stars because shipping took a bit longer than expected.

Premium feel
These replace the cheap plastic knobs on my amplifier beautifully. The weight adds a nice tactile feel when adjusting volume. Highly recommended.

Bulk order success
Ordered fifty units for our workshop. Consistency across all pieces was impressive. The set screws included were a nice touch.
Q: Do you offer a 30mm diameter option?
A: Currently, we only stock diameters of 17mm, 21mm, 24mm, 25mm, 38mm, and 4mm. We do not have a 30mm version at this time.
Q: Does this come with the screw needed to secure it to the shaft?
A: Yes, each knob cap includes a matching set screw for secure fixation to the 6mm shaft.
Q: Are these suitable for high-temperature environments?
A: Aluminum alloy has good heat resistance, but please ensure the specific operating temperature of your device does not exceed the limits of the anodized coating or surrounding components.
Q: Can I use this on a shaft that is slightly smaller than 6mm?
A: The inner hole is precisely 6mm. For smaller shafts, you may need to use a shim or bushing to ensure a tight fit, as the set screw alone might not hold securely.
Q: Is the red color a bright fire-engine red or more of a dark maroon?
A: The red finish is a vibrant, standard anodized red, similar to a fire-engine red, not maroon.
