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

These copper wire lugs are formed from heavy copper, pressed, and stamped. They’re not thin and bendable like so many are. These are going to hold solid and last. I got the 8 AWG for my commercial lawn mower and other attachments on vehicles that use this size. Amazon Vine sent this product to me for an honest unbiased review. Would I recommend it? Yes, these are quality, solid copper lugs.

I used some of these to build new golf cart power leads. They were easy to crimp, and hold secure. I actually crimped them down to 4ga, as I bought 2ga by mistake, but since they are copper, they crimped fine. I will probably tin the next few for longevity, and to protect against dissimilar metals on certain areas they are attached.

I use these to install battery cables for amplifier kits (or large inverters). They crimp nicely and cleanly. I can really mash these with my hydraulic crimp set and they wont split open. All wire you purchase can be different diameters, given a specific gauge, so keep that in mind. These fit 3 different brands of 1/0 wire I had on hand and the opening of the lug matched some other brands of lugs I had. Finish off with a small piece of shrink tubing and it looks great.

I ordered these ring terminal to build high voltage DC cables for an EV conversion project. They are very good quality, the copper is nice and thick and the product is well finished with smooth edge and no burrs to be found. The flared ends make sliding the stripped able into the fitting easy and without issues with rogue strands getting bent out in the process. It may seem like a small detail but I like that they are all marked with the wire gauge and hole size so there is no guessing on the size once the package is gone. They crimp well with my crimp tool make a nice solid connection on the cable end.

Used to hook up power cable for a winch on my equipment/car trailer. Will have to wait to see how they hold up in weather. Easier to use if you have a lug crimper but could be done with larger pliers. Filling the end with solder or dielectric grease should help to keep corrosion between contacts to a minimum. Stud size is perfect for this use.

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.

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.

I had a hard time finding these locally. I needed to swap out the work clamp on a welder and I was also trying to build a separate work lead with a magnetic ground. But all I could find locally in this size was tin plated copper in 2 packs for about $5. This is non-plated regular copper in a 10 pack for $7! Great deal and served my purpose exactly as I had hoped.

Great copper wire ring terminals, I am using for a high power go kart build with 4awg wires. Perfectly sized, fit my 4awg wire perfectly and took solder without any complaints. Would recommend, as I am using 5 pcs just for one project in a brushless controller setup. Thick terminal rings, not flimsy at all.

With a product like this, its either going to be great or absolutely horrible. I am happy to say these were great. They fit my 2/0 awg wire perfectly. You could probably solder them to the wire, but I ended up crimping it with a hydraulic crimper.
