10Pcs 4mm Banana Plugs Solder DIY Banana Plug Connectors Adapters for Multimeter Test Leads Probes

I liked that there were different color and for the different meter leads I bought 14 gauge silicone wire on Amazon, which is very flexible like a meter lead. You definitely need to tin your wires and the connector and heat it 700° to get a good solder joint there is plenty of space for the solder still leaving room to snap the end in place you will need to heat the plastic part up with a heat gun to snap it into place. these were perfect for my needs.

These have a great fit and finish and make an excellent connection. The pin can swivel in the jacket, which is a nice touch. The only drawback is that they are a little difficult to assemble until you figure out all the tricks (which I gleaned from a couple other reviews here).Slide the jacket over the wire first. Strip the wire just enough that the exposed conductor is the same length as the "solder cup" in the plug. Tin it. Tin the "solder cup" in the plug. Be patient, it takes a LOT of heat to get the solder to bond to the pin. Feed the wire in and solder the exposed conductor to the pin, filling the solder cup with solder. Again, be patient as this takes a lot of heat. I was using silicone jacketed wire, so I wasn't too worried about how hot the wire got. Once soldered, you will find it seemingly impossible to slide the jacket over the pin. The trick is to heat the jacket a little bit with a heat gun. Just a few seconds with a crafting heat gun on the lower setting was all it took for me. Don't pull the wires to seat the pin in the jacket. Although the solder connection is very strong, you don't want to tug on the wire hard enough to snap the pin into the jacket. Instead, holding the jacket, press the tip of the pin against something that gives a little, like wood. It should give a satisfying snap. If it still refuses to go in, try heating the jacket a little more.Once assembled, these are great.

As in the title, I think they work very well. They seem sturdy and durable, certainly much better than the flimsy cheaper connectors found everywhere. I was able to solder them without any issue. However, the plastic sheath sometimes is exceptionally hard to slide in, I had to use pliers and a lot of force in multiple attempts.

Excellent quality! These will far outlast the cheap meters I am using them on!

The banana plugs themselves are properly sized and fit well in everything I tried them in, but the sheaths don't fit over the banana plugs. Had to ream them out just slightly or the plugs wouldn't slide all the way in to the proper place, leaving the solder point exposed.

Other reviewers complained about the tight fit of the cover. I gripped the cover with pliers and pressed until it snapped on the metal plug. I'm not a particular strong person. I liked that it was a tight fit. Soldered wire to the plug and measured only miliohm resistance. The plug fit snugly into my Fluke multimeter. Seems like a good product.

Believe it or not, there is NOT clearance to allow the metal plug insert to fit all the way into the nylon sheath! I have seen other reviews recommending modifying the sheath with heat but that can also easily melt and deform the sheath material (in ways you don't want!).There are other reasons not to buy these! 1) The OD's of the banana portion of the plugs vary and result in overly tight or loose connections when inserted into female sockets, and 2) the insulating sheath material is so hard (no give at all) that the strain relief is rendered useless.NOT worth the trouble and aggravation!!

Great quality banana plugs so far. They seem to take up to AWG 14 sized wire.They are solder plugs, not crimp, and require quite a bit of force to snap together.Key point is that they plastic jacket and strain relief needs to be threaded on the wire FIRST!Here is what I did:1. Thread jacket on wire2. Strip small amount of wire3. Flux the exposed wire4. Pre-tin the solder cup on the plug5. Mate the wire and plug6. Solder7. Grab the jacket with pliers and push DOWN into the plug (on a piece of scrap wood)You should feel a noticeable "click" when it is fully mated and seated properly. The resulting plug feels very solid. Just dont forget to use a piece of wood, as you can see in the last photo the amput of pressure let divots! (Ok, it is a piece of Fir, so it is soft wood to begin with, but still... You get the point.)Enjoy!

excellent quality, easily soldered I had to use a heat gun to soften the plastic casing to get it to slide over the soldered end

Three stars? A bad product? Not at all. They work fine and if you are not pulling them out and inserting them into different components all the time, they will be just fine. But they are just a light weight plastic. I don't think they were ever intended for heavy use. Like in a studio setting. But my applications are not like that. I will make a project and then not worry about any kind of dis-assembly. My will stay connected. And for that kind of use, these are fine.Bottom line is that they work. They fit well into my connectors. If you are careful with them, they should be fine. Just remember, they are not heavy duty. They are light weight connectors. I think the old adage, "You get what you pay for" applies here.Paid for with my own money. Thanks!
