Sturdy and reliable

Been using these for three months now on a daily basis. No signs of wear on the anodized finish. Definitely buying more for my next project.

Perfect fit for my DIY amplifier

The build quality is exceptional. The aluminum feels premium and the 6mm hole fits my potentiometer shafts perfectly without any wobble. Highly recommended for audio projects.

Good value for money

Nice aesthetic upgrade for my custom electronics box. The only reason for 4 stars is that the set screw provided was slightly short for thicker shafts, but I had a spare.

Exactly as described

Fast shipping and the item matches the description perfectly. The inner plastic insert grips the shaft well, and the outer aluminum adds a nice weight.

Great look, minor installation note

Looks fantastic on my sound card interface. Just make sure to tighten the set screw firmly as the smooth shaft can slip if not secured properly. Otherwise, a solid product.

Professional feel at a great price

I replaced the stock plastic knobs on my mixer with these. The difference in tactile feedback is night and day. Very precise turning action.

5 FAQ

Q: Is the inner hole exactly 6mm or is there some tolerance?

A: The hole is manufactured to a standard 6mm specification with a slight tolerance to ensure it fits standard potentiometer shafts smoothly without being too loose.

Q: Does this knob come with the necessary set screws?

A: Yes, each knob includes one small set screw for securing it to the 6mm shaft.

Q: Is the black version available?

A: Currently, this specific listing is for the Silver finish only. Please check our store front for other color options which may be listed separately.

Q: What is the outer diameter of the knob?

A: The outer diameter of the aluminum cap is approximately 25mm, making it comfortable for fine volume adjustments.

Q: Can this be used on a 1/4 inch shaft?

A: No, this knob is specifically designed for 6mm shafts. A 1/4 inch shaft is approximately 6.35mm and will likely be too large to fit.
