10Pcs Safety Fully Insulated Multimeter Test Leads 4mm Banana Plugs Male Stackable Connectors with Banana Jack Adapters

Been wanting to start making my own leads for low voltage and amp projects, not cause I'll make better ones but because cost and learning opportunities. These will be used as my first round POC portable digital voltmeter and ammeter. Pretty excited about these leads. So far, my initial tests show good quality on the banana jack adapters, they fit most of my other multimeter lead sockets. But the best part is the idea of stackable test leads during a test because sometimes.....

Solid well built

hard to work with

I ended up purchasing different connectors with the screw-on wire connector, these were hard to solder without the wire getting too hot.

I used AWG 18 stranded on these; the sprung hooks on the other end couldn't handle anything thicker. These plugs, however, would take much thicker wire. AWG 14 might be easier to solder in place than the thinner 18 gauge wire I had to use. After tinning the ends, I inserted them through the interior pins (there's a cavity there). It took a good bit of heating from my venerable Weller soldering station to get the pins hot enough to bond test lead, pin, and solder into a solid connection. After assembling the three pieces (plug, interior pin, upper shroud), the final result was solid. The parts snapped together firmly and the test lead was securely captured. These can be repaired, if necessary, making them a decent investment.

The media could not be loaded. They work well and are high-quality. They fit perfectly on my harbor freight Cyntech Multimeter. It’s nice to use your own high-quality wire. They are stackable and you can put the stock leads at the top.

Really nice set of test leads and the price is right. They snap together very clean and tight. I was expecting them to feel like stiff cheap plastic but was happily disappointed. I prefer these stackable versions to help make taking measurements easier...

They work well in all of the insulated banana jacks ony tear equipment. Some older stuff that isn't made for insulated banana won't work, as others have stated. Anything that a fluke meter lead fits seems to work well with these. I used them to repair some broken fluke leads as well and they are great quality and don't come apart easily. 10/10 would recommend.
