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

I would call these terminals medium duty. If they get too thin they may not hold the crimp and the type of crimp used also makes a difference. If used in a severe environment these terminals could be soldered if needed. I’m happy with these terminals. I’m using these to install a DC to DC battery charger.

Ive purchased several copper lugs for heavy duty solar wiring. These seem as good any of those. I go the 0 AWG size, and the cable fits easily but snuggly into the lug--thanks to the flared end of them. And it is easy to crimp.

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.

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

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.

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.

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.

Plenty of copper to crimp down and hold the wire in place. Feel good and solid. Got the job done.

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.
