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

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 the 4AWG 5/16 terminals and when I first received them I thought I had the wrong gauge. They appear much larger than some other existing 4awg terminals I have. Upon further inspection, I think theyre actually better quality. Using a micrometer, I measured the same internal diameter as my others (about 7.5mm), and this one is actually a little more round. I think 2 things make it look larger. The first is it has a flared end where the wire goes in, and the second is that it fully encloses the wire. The flared end is is good to help you insert the wire, but on the other hand it could be harder to crimp flush with your wire. This terminal is also thicker than my others (2mm). Additionally, when the wire is fully inserted, it will not stick out the other side as theres no opening opposite the entry; it is fully enclosed. Overall, this seems to be a good quality terminal.

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.

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.

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.

These copper studs crimp easily and securely. They are just as represented in the product description.

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.

Fixed my ground that had the old bracket snap off. Works perfect.

Im doing a wiring project with #6 wire, and these make excellent terminations. I have a nicro press tool I use on my boat, and that crimps these terminals nice and tight. I do put dielectric grease in, maybe unneeded, but its a habit.

Yup these are exactly what they say they are.they work just fine for the suv I will be using them on to mount new grounds and lights.
