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

They were great quality and price was right

Smaller than 0 gauge

Perfect

Item as described/solid copper. However, if you have Sky High Audio 4/0, these are half the size of the stranded wire. These would fit Sky High 1/0, maybe 0awg, it would be tight.

no issues

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.

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 !!!!!

These were perfect for the inverter and batteries I installed on our camper.

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.

A lot of pieces for the price.
