150PCS Copper Ring Terminal Open Barrel Wire Crimp Copper Kit M3/M4/M5/M6/M8/M10

Although I purchased these in 2020 and they may have changed since then, I feel that I must post my impression of what I received. These have been sitting unused on the shelf since purchase.The listing shows that the material these ring terminals are made of is copper. I tried to crimp these terminals and found them almost impossible to crimp. I thought the copper (or probably brass) had hardened from forming so I annealed a terminal & found no change, which I found rather curious. Just for grins I held it up to a magnet & found that it stuck to the magnet indicating that the terminal was made of iron or steel! I checked the rest of the terminals & found that they were also magnetic. They are going into the scrap metal pile as they are not usable.Hopefully they have changed the material the terminals are made from & upon purchase you should check before the return window closes.

I got these to rewire a replacement fuel pump on my car. The gauge seemed a bit light, so I used 2, one on each side of the wire to stiffen the assembly up. They soldered well, look to be up to the job.

They are a little thin

A little thin for crimp only, would plan on soldering if I were you, but really easy, nice product.

I liked the variety of sizes and that they came in a case. There are a lot of them but that's OK too.

Thin and cheap

Great. No problem. I expected what I got. Thank you.

Very very thin. I don’t then they are brass.
