5Colors Safety Fully Insulated Test 4mm Banana Plugs Male Stackable Connectors with Banana Jack Adapters for Multimeter Test Leads Probes 10Pcs

Great for making custom test leads. I use with 14ga silicone wire. Works with multimeters and Power Probe.

Good quality, and great price, acompanied with a snug fit in you’re test leads or DMM

Perfect for making test leads for my automotive technician work

Nice and small. Cons: It takes a lot of heat to solder the wire in, so the plastic tip will most likely melt. You can avoid that by simply plugging it into another receptacle/plug while soldering it. Don't heat it longer than necessary to create a good soldering (See pictures). This plug support 12 AWG copper/stranded if needed, but you'll have to drill out the plastic hole to 4mm for the insulation. There's one other stackable safety banana plug available on Amaz (red/black-gray), but it is big and clunky but barely supports 14 AWG. I purchased both types. Pros: It has a screw terminal to fasten the wire, no soldering and no plastic tip - The metal part fits the plastic housing of theother plug with the plasic tip.

Wish I had found these years ago. Require a little soldering, but make use of test leads much easier and hold up well.

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.....

No way to mechanically attach wire to terminal. If you solder the wire the red plastic tip starts to melt. Need to know my test leads are 100 percent reliable.

Worked to my plan, easy to use.
