Great knob, minor fit issue

The knob looks amazing and feels very solid. I had to slightly adjust the set screw tension, but once installed, it works flawlessly.

Precision engineering

You can tell this was made with high-quality CNC machines. No burrs, smooth edges, and the dimensions are exactly as advertised.

Sleek and sturdy

I bought this for a custom audio project. The toothed design provides excellent grip, and the anodized finish matches my other components perfectly.

High-end look without the price

Replaced the plastic knob on my CD player with this aluminum one. The difference in tactile feedback is night and day. Highly recommended.

Perfect upgrade for my vintage amp

The build quality is exceptional. The CNC machining is precise, and it fits perfectly on my 6mm shaft. It adds a premium feel to the volume control.

Solid addition to my setup

Very happy with the purchase. It's heavier than expected which gives it a nice premium feel. Took one star off only because shipping took a bit long.

5 FAQ

Q: Is the set screw included in the package?

A: Yes, the package includes one volume knob and the necessary set screw for installation.

Q: What tools are needed to install this?

A: You typically only need a small Allen wrench (hex key) that fits the set screw, usually 1.5mm or 2mm depending on the specific screw provided.

Q: Can I use this on a potentiometer with a flat shaft?

A: This knob is designed for D-shaped shafts. While it might sit on a flat shaft, we recommend using a D-shaft pot for secure attachment and proper rotation.

Q: Is the black finish prone to scratching?

A: The knob features a hard-anodized finish which is quite durable and resistant to minor scratches, though care should still be taken during installation.

Q: Does this knob fit a 6.35mm shaft?

A: This specific model is designed for a standard 6mm D-shaft. For 6.35mm shafts, you would need an adapter or a different model.
