Aviation Connector GX12 4 Pin, Lsgoodcare 10Pairs GX12-4P 12MM Thread Male Female Wire Panel Metal Connector Plug 5A Circular Aviation Chassis Mount Socket with 10Pcs Aviation Caps

Excellent 4 pin plugs. I’m using these to plug in a red, green and blue 12volt led light strip. They work well, have a good tight fit to them and screw down nicely to prevent the connection falling out.Perfect for what I needed.

They are fine and useful, except the nuts do not tighten the screw to the panel because of a thread loss, and the nuts go out every time.

I bought these for a valve Phono preamp I'm building. They're not bad, but not the best. Easy up on the soldering iron heat, as the plastic melts very easily when soldering wires. The pins also take a while to solder. Something to do with the plating. Also some of the buckets in the pins are different size, so if the wire you're using is a thicker gauge, you will struggle.Over all though, they are OK. They did the job for my purpose. Whether they last, remains to be seen.
