25 pcs WNI 4 Gauge x 5/16 Pure Copper Battery Welding Cable Lug Connector Ring Terminals

The item is high quality and works perfect for solar battery system

I purchased these 5/16 as well some with 3/8 hole fittings, I used the 3/8 on the battery terminals and these fit nearly everything else, The starter, the new Fuse link I added, the alternator (with some filing down), I stuffed some solder in the fittings, wrapped the wire with some more solder, slipped on some shrink tubing, shoved the 2 ga wire in fitting all the way to the sheeting, I then used my hydraulic crimpers (which I loved) and crimped the connectors on, I then too a small butane torch and melted the solder, after it cooled down I slid the shrink wrap over it and heated to make a nice clean connection - These fittings worked perfect !!!!!

Good quality product. Just what I was looking for. Will order from them 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.

Product was just what I wanted,a sturdy strong copper terminal and fast shipping.

A lot of pieces for the price.

Looks great just put ininventory
