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

These terminals have really come in handy with a welding machine rebuild that I’ve been working on. They went on the cables easily and are very durable. Would recommend these

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.

No problem inserting the correct size awg wire and soldering the lug onto the wire. I did use flux and had no problems with adhesion. Worked just fine. With they had a size between the 1/2” and 1/4” hole. I’m sure 3/8” or 5/16” would be the most popular for the hole size. I used the larger 1/2” hole and put a stainless washer over the lug so it could be secured.

These are good quality lugs that fit my wire and crimped perfectly. How My Star Rating System Works & What They Mean: 1 STAR - Pretty much junk and I would return and ask for a refund if I could. 2 STAR - It works, but barely meets the minimum requirements it should in order to keep it and not return it, but I would not order again. 3 STAR - It does what it was designed to do, but theres nothing really special about it. Its acceptable but not great. 4 STAR - I am very comfortable recommending it to a friend because it is is well made, durable, and delivers on its advertised features, and I would buy it again. 5 STAR - I really love it. The item exceeds my expectations of quality, durability and functionality. Not only would I purchase it again, but I would also actively encourage friends and family to to do the same. All of my reviews are my own personal opinion and are completely honest no matter if I receive an item for free or I pay for it. I am an avid Amazon shopper, as well as an Amazon Vine Voice and I personally rely on reading reviews to make all of my buying decisions, so I understand the importance of honest reviews from my peers.

Exact size I wanted

I have a decent sized solar setup and I am constantly upgrading or changing things around. I go through a fair amount of terminals, mainly in setting up the connections between the various battery banks and the inverter. These lugs are copper, fit perfectly, crimp and solder easily. Exactly what I wanted. 5 stars for matching description exactly. Note: I have been an Amazon customer for almost 20 years. I write all of my reviews to reflect my personal observations and opinions on a product. It matters not if I have purchased the item myself or if it was provided to me for review. My goal is to provide other potential customers as much real-world knowledge as possible to make an informed decision. In most cases I will return to my review in 6 months or less to see if I should alter my original observations. In no case will the cost of a product influence my opinions at all. In addition, I will try to include multiple images and or videos on each product, if practical.

These are copper and are well made at a great price point.

Made of solid copper ! Nice, good size hole to fit different sizes fittings! But not made of ground welding wires.

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.

Good quality, heavy gauge copper wire lugs. Machining and stamping is done very well. It has a 5/16 or about 8mm ring terminal. Only other thing youll need to make quality high amperage connections is the crimping tool (see the snap-on version in my photos) and a little heat shrink tubing. 5 stars
