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

Great terminals. I wish I had found these a while back. I've ordered parts for several different variations to hook up to multimeters but this works best no doubt. Fitted 12v automotive copper into the hole (which is actually a well from which solder forms a slug bonding and trapping the wire in the fixture). You won't regret buying these terminals.

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

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.

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

The pin does not take solder well. If I need to make another test lead I will rough up the inside with a drill, which should help. Otherwise the quality is quite good--the pin and two component parts fitted together with a snap and seem very secure. I hope the solder connection holds up.

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.....

Perfect for making test leads for my automotive technician work
