Good quality, slightly loose initially

The build quality is solid for the price. It was a tiny bit loose at first, but after tightening the set screw (if applicable) or pushing it firmly, it sits securely. Works great with WX110 series.

Perfect fit for my vintage radio repair

This knob fit perfectly on the 6mm shaft of my old WTH118 potentiometer. The gray color matches the original aesthetic well, and the copper core ensures a tight grip without slipping.

Exact replacement part needed

Hard to find specific knobs for these older potentiometer models. This one is an exact match for the inner diameter and depth. Highly recommended for restoration projects.

Great for student projects

Bought this for a university electronics project. It looks professional and functions smoothly. The gray finish doesn't show fingerprints easily which is a plus.

Does the job

Simple, effective, and cheap. It's not luxury material, but for functional replacement on a WX112 pot, it works perfectly. Shipping was fast too.

Sturdy copper core

I appreciate that it has a copper core rather than just all plastic. It provides much better torque transfer when adjusting sensitive circuits. Will buy again.

5 FAQ

Q: What is the outer diameter of the knob?

A: The outer diameter is approximately 18mm, providing a comfortable grip for precise adjustments on standard panel mounts.

Q: Can this be used with WX114 models?

A: While it fits the 6mm shaft common to many models, we officially list compatibility with WTH118, WX110, WX111, and WX112. Please verify your specific shaft dimensions before purchasing for WX114.

Q: Will this fit a potentiometer with a 6.35mm shaft?

A: No, this knob is specifically designed for a 6mm inner diameter. It may be too loose for a 6.35mm (1/4 inch) shaft without an adapter or shim.

Q: Does it come with a set screw?

A: This specific model relies on the friction fit of the copper core and does not include a separate set screw. It is designed to be pushed firmly onto the shaft.

Q: Is the copper core visible from the outside?

A: No, the copper core is internal and serves as the gripping mechanism for the shaft. The exterior is entirely matte gray plastic.
