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

Great set. Currently using continuous @ 6V 1-3A in an electrolysis tank. Despite limited exposure to solution & continuous 8 hour a day usage, has held up perfect.Note that you need to solder & crimp these. That being said, solid option if your comfortable with that.

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.

These are well made the only thing I have against them is you will need to heat the body so you can get them on

Extremely hard to solder to, and the plastic covers are extremely difficult to install.

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!

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!!

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