Essential for luthiers
I keep a box of these in my workshop. They are indispensable when swapping out pots or fixing loose knobs on customer guitars.

Solved my wobbly knob issue
My volume knob was spinning freely. These replacement nuts and washers tightened everything up instantly. Very satisfied.

Great value kit
Good quality for the price. The washers are thin but sturdy enough for standard guitar knobs. One cap was slightly loose, but the rest were fine.

Perfect fit for my Stratocaster
These caps and nuts fit perfectly on my vintage-style pots. Having both metric and imperial options in one pack saved me a trip to the hardware store.

Highly recommended
Excellent little parts. The screw caps look professional and match the original hardware on my Les Paul perfectly.

Decent but mixed sizes
The quality is okay, but I wish the packaging labeled which specific size was which more clearly. Had to test fit several before finding the right one.
Q: Does this come with a tool for installation?
A: No, this package contains only the screw caps, nuts, and washers. You will need your own small wrench or pliers for installation.
Q: Can I use these for bass guitar pots?
A: Absolutely. As long as your bass guitar uses standard electric guitar potentiometer shafts, these components will work perfectly.
Q: Do these fit CTS potentiometers?
A: Yes, this kit includes imperial sizes specifically designed to fit standard CTS pots commonly found in American-made guitars.
Q: Are the nuts made of plastic or metal?
A: The nuts and washers are made of a durable metal alloy, while the screw caps are high-quality plastic to prevent scratching your knobs.
Q: What is the difference between the metric and imperial sizes included?
A: The imperial sizes fit US-standard pots (like CTS), while the metric sizes are suitable for imported guitars using Asian or European standard pots.
