Hilitchi 240Pcs Tin-Plated Copper Non-Insulated Ring Crimp Terminals Assortment Kit - Open Barrel Wire Electric Terminals for Solid & Stranded Wires (M3 M4 M5 M6 M8 M10)

I don't usually do a bad review.. but these things were a joke.. so flimsy and cheap..I sent them back

Great value

Good selection but it seems that some are too thin to last. Quality roll crimp terminals are difficult to source in a bulk selection so therefore I will keep these for light duty use. The price was reasonable.

A good selection of ring connections

Bought for my nephew and he loves it.

As soon as I tried to bend one of these "Hilitchi Tin-Plated Copper Non-Insulated Ring Crimp Terminals" I doubted that they were copper, so I got out the file and, guess what? These terminals are definitely *NOT* copper. They are actually brass, which is only 28% as conductive as copper. See the attached photos. This means that not only are they no good for carrying current, they also aren't good for accurate voltage-sensing lines either, because they will produce a slightly low reading. They also are *NOT* tin-plated (looks like they might be nickel plated, which is OK, but they might have some form of cheap chrome plating, which isn't great for conductivity). And lastly, they are also VERY THIN too, measuring only 0.37mm thick (about 0.0145 inches, which is less than 1/64th inch).

Quality lugs. Not much more to say.

The kit is a nice range of sizes however the metal is very thin and weak. Might be ok on thin wire.I have a professional crimping tool but couldn't get a good crimp on much over 18 gauge.Cables I put together for connecting to an RV battery with 12 gauge literally fell apart. With a bit of solder afterwards they would have been ok.
