Great for Arduino projects

Very easy to install on 6mm shafts. The textured surface makes adjusting values precise. Highly recommend for any hobbyist building control panels.

Perfect fit for my guitar pedal

These knobs are exactly what I needed to replace the worn-out caps on my vintage pedal board. The grip is excellent, and the set screw holds tight without slipping.

Reliable and sturdy

I've installed dozens of these on mixing console modifications. They don't crack under pressure and the screw mechanism is robust. Will buy again.

Good quality for the price

Solid plastic construction. I used the MF-A03 model for a custom synthesizer project. The only minor issue is that the color was slightly darker than the photo, but it works great.

Nice replacement caps

Bought the white ones for a retro kitchen radio restore. They look authentic and feel sturdy. Took off one star because shipping took a bit longer than expected.

5 FAQ

Q: Do you offer these in bulk packs?

A: Currently, this listing is for single units. However, if you need quantities over 50, please contact our sales team directly for a bulk discount quote.

Q: What is the difference between models A01 and A05?

A: The primary differences are the outer diameter and the height profile. A01 is generally smaller and lower profile, while A05 is larger with a more prominent grip. Please refer to the dimension chart in the product images.

Q: Can these withstand high temperatures near amplifier tubes?

A: These are made of standard ABS plastic. While they handle normal operating temperatures well, we do not recommend installing them directly next to high-heat sources like power tubes.

Q: Does this knob fit a 6.35mm (1/4 inch) shaft?

A: This specific series is designed primarily for 6mm shafts. For 6.35mm shafts, you may need an adapter or a different model series. Please check the detailed dimensions before purchasing.

Q: Is the set screw included in the package?

A: Yes, each knob cap comes with one small metal set screw required for mounting.
