    Good value. They were just as described. They worked great for the 4 gauge wire that I used. I crimped them and have had no problem. I would buy again.

    As Amazons photo is so crystal clear, so; I didnt like 3/8 hole along with not enough of copper around the hole. I had decided to get 5/16 for tightly fit my batterys bolt, that I had really love. I had though, to bore the 5/16 at 1mm. larger for fit, that I didnt have to.
