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

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.

They are OK. What more can you say about terminals? They are not Autozone trash. They will support the Amperage required of the wire that can be inserted.

For solar, emergency power, or your boat, these connectors are perfect and high quality.

Great product for the price

Used on golf cart. Worked great

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 !!!!!

Oversized for 2 gauge cable if soldering, larger than expected for 2 ga flex cable non tinned copper.

A lot of pieces for the price.

Works good for my project
