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

Best quality and price I could find for copper 4 gauge 5/16 lugs. Have bought a second package for a solar install. Will purchase more as needed.

Heavy copper. Hard to crimp. I replaced battery cable ends on 3 rv batteries. Old ends were steel and rusty.

great product

I find the product acceptable and it works as advertised.

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.

Nice heavy one! They crimp nicely.

Worked great for the application it was used on

Not much to say. Theyre true copper, thick enough to get a quality hammer crimp even on heavy 7-strand wire. Good connection and arent corroding at all even months later. Was capable of drilling one out to take a 3/8 lug without the bit grabbing it and turning it into a pretzel, which also says something.

Quick delivery.

Works well
