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

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

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 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.

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.

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.

I do like that these guys have very specific ring sizes as well as (obviously) being for specific sized cables. Im a stickler for the 2-hole, 2-crimp method wherever possible, but its usually not possible outside of grounding and bonding, so these are pretty nice.

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.

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 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.

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