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

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 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.

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.

Just what I was looking for I used it on my zero turn lawnmower and it worked great

These are first rate terminals made of 100% pure copper for excellent conductivity! The quality is very nice, with terminal size clearly stamped, and they are accurately sized for the wire gauge they represent. Very good value!

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.

I got the 8 AWG - 1/4 lugs. They have a nice thickness. I cut into one with a Dremel and it seems to be solid copper. An 8 AWG wire fits fine and a 1/4 bolt fits the ring with only a bit to spare. Exactly what I needed!

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.

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.

These are a basic set of lugs, and they do the job well. They are not UL listed, but if you don’t require that they are more than adequate. I use them in small solar projects I have, and I do not have any issues. I scraped through a few layers of metal, and it looks like copper all the way through. Overall, a solid product.
