[5pcs] 4 Awg - 3/8 Stud, Copper Wire Lug, Ring Terminal, Battery Cable End, Cable Lug, Wire Connector by KeeRoarin

Get er done! Heavy duty battery cable ends. Made of Copper ready to install

quality product for the price. holds good with solder. crimps nice dont break apart like other brands.

These are a nice set of 10 lug connectors - on par with some others i’ve had before. I have a crimper, and these work well with them. Decent quality. Very nice.

Exact size I wanted

I ordered the 2/0 terminals for an inverter setup for my vehicle. These things are beefy, as expected. They crimp well and have lots of contact surface to make a good connection. I am very happy with the build quality, these things look like they will last.

These make very nice finished looking wire segments when wiring in 12 volt accessories to our golf cart. I try to remember to slip on some shrink wrap before crimping for an even more finished look. I got these specifically for the large lug opening.

Decent enough lugs to get the job done. Crimps easy enough to wires and carries power through them without making a hot spot when used appropriately. Using these on the terminals of 24V lifepo4 batteries in parallel to upgrade some UPSs life and runtimes, they are doing decently so far. Should last the life of the device.

Worked perfectly along with a hydraulic crimper for making new battery cables. Thick copper, flared opening to make getting the wire in easier, good quality.

These KeeRoarin copper wire lugs are actually copper all the way through unlike many which when crimping on you realize are copper coated. These are excellent quality lugs and I have installed a few on some electrical battery connection cables that needed to be remade. Excellent quality product but be sure you have the correct crimp tool for creating a solid connection.

I got the 6 gauge 5/16(M8) lugs. Im using these on 4 gauge WindyNation wire. I found out that you cant match wire and lugs using gauge alone. The actual decimal diameter of a manufacturers gauge of wire varies a lot depending on the stranding, and bunching of those strands. Lug manufacturers tend to go larger with their ID to accommodate more wire designs. To get the best connection, you want the wire to fit snugly in the lug prior to crimping. If its way loose, your crimp will look bad and the connection will likely be poor. I always match the OD of the bare wire to the ID of the lug, and use gauge just as a loose reference. These lugs are about average in thickness. I measured these at .060. I have others that are .075, and I prefer that thickness. However, these are wider. That extra width allows more contact surface on my bus bars, battery terminals, etc. I think the extra width, and therefore extra contact area, is more important. The terminals fit my wire perfectly and crimp nicely. It would be nice if they came with heat shrink tubing, but theyre otherwise just about perfect. I recently also got the 1 Awg terminals and had the same great experience. The copper was thick enough, and the terminal itself was wide. These are well made terminals, and they were perfect for my needs once again.
