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

Good quality

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

Looks great just put ininventory

I am a car audio installer working on a personal project. I purchased these to install on 4 gauge OFC wiring and they fit perfectly.

Upgraded all the cables on my ezgo golf cart from 6g to 4g. Perfect product for application.

Work great

Goo0d part and very rigid

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 !!!!!

Worked out great, would buy again

The WNI 1/0ga x 5/16 lugs are great...as long as youre NOT using Sky High Car Audio 1/0 wire. It wont fit without cutting strands. If youre using GP Car Audio, Knukonceptz or most any of the other brands of 1/0 car audio wire you should be good. The fit is snug on the wire. No issues using the hydraulic crimper.
