Exactly as described

Dimensions are accurate. The knurling provides good grip. Shipping was fast and the item was well packaged to prevent scratches.

Solid construction

No complaints here. The metal is thick, not thin sheet metal. It matches other silver components in my setup perfectly.

Nice upgrade from plastic knobs

Replaced the cheap plastic knobs on my old pedal board with these. They look much better and feel more durable. Took off one star because the set screw could be slightly longer.

Perfect fit for my amplifier project

The build quality is excellent. The aluminum feels solid and the brushed finish looks very professional on my DIY amp. The 6mm hole fit my potentiometer shaft perfectly without any wobble.

Good value, minor machining marks

Overall a great knob for the price. There were some very faint machining lines on the side, but nothing noticeable once installed. The set screw holds tight.

Heavy and premium feel

I bought ten of these for a modular synth build. They add a nice weight to the controls which makes adjusting parameters feel precise. Highly recommended for metal chassis projects.

5 FAQ

Q: Does this come with the set screw needed for installation?

A: Yes, each knob cap includes one matching set screw required to secure it to the potentiometer shaft.

Q: Will this fit a shaft that is 6.35mm (1/4 inch)?

A: No, this knob is specifically designed for a 6mm shaft. A 6.35mm shaft will likely be too large to fit without modification.

Q: What tool is needed to tighten the set screw?

A: A small Allen wrench (hex key), typically 1.5mm or 2mm depending on the specific batch, is required to tighten the set screw. One is not included in the package.

Q: Is the finish matte or glossy?

A: The finish is a brushed matte silver, which helps reduce fingerprints and glare compared to a polished glossy finish.

Q: Can I use this on a D-shaped shaft?

A: This knob has a round 6mm hole. While it might physically slide onto a D-shaped shaft of the same diameter, it may spin freely unless the flat side is very small or you use an adapter.
