10 Pcs 4mm Banana Jack Female Panel Mount Banana Socket Binding Post Adapter for 4mm Banana Plug Connectors

Seem to be of decent quality, like value for the money. All the colors are nice looking except for the yellow ones, they are too lemon looking, they should have a little more of a darker color yellow.

Overall these were great and I'll buy them again next time I need some. They locked securely with the nut, and fit 1/4" spade terminals. She the images if you need dimensions. Some of the other reviews mentioned the holes being off-center. All of these were fine for me. I would definitely buy them again.

I am impressed. I heated the heck out of the base of the tab to solder a buss wire 350C Iron for nearly a minute yet the plastic did not even change color. The nickle coating makes the plug on spade lugs work well. I did not find any with concentricity problems.

Did not find any with the center post being off-centered but did find the screw nut is looser than necessary and can be easily cross-threaded. The base material seems to be brass but it is tin plated. The only part that is found to be magnetic is the thin washer. Tested one of each color for voltage drop with a 10A load and found it to vary between 30-32mV so not too bad. Insertion force is smooth and reasonable. Will buy again if needed.

Worked as expected. Fit well. Good value. Connected well too.

Perfect

Useful for electronic projects.

Just what I expected.
