SELTERM 10pcs 4/0 AWG - 5/16" Stud - Wire Lugs, Heavy Duty Battery Cable Lugs, Ring Terminals, Battery Cable Ends,0000 Gauge Terminals, UL Bare Copper Eyelets Electrical Battery Terminal Connectors

I have purchased a few different brands and they all ended up being pretty cheap. If you are looking for nice thick copper connectors, then these should do the trick. They crimp just fine and provide a solid connection. Add with them some adhesive shrink tubing, and you'll have a connection that will last.I purchased the version for 6AWG wire which fit perfectly with the wire I have.Pros:Nice thick copperStill easy to crimpPlenty of copper left around bolt holeEasy flared end to help with getting wire into holeCons:None

If you're looking at these for car audio, 0 gauge 5145 strand ofc wire, THAT IS AN OVERSIZE WIRE! You need these 2/0 guage terminal lugs to fit that wire. I wish someone would have told me this, i had to figure it out for myself.THESE ARE ABSOLUTELY PERFECT for car audio applications offset foot pad allows it to lay down flat. And if you got more than one going to a bolt and there's room you can put the foot cats back to back and they still lay down flat on each other. HIGHLY RECOMEND the adhesive lined shrink tube to use with this also HIGHLY RECOMEND getting using the hydraulic crimper not a hammer crimper. The hydraulic crimper makes you crimp look clean and professional. I got the 16 ton. The $50 i spent on that crimper was money well spent because of how easy it is to use and how much crimping force it exerts on the lugs. And when you're done with your project you can rent it out to your friends and get your money back!

While not quite superconducting, my fusion reactor did put out a few more millions of neutrons a second after I used these in my prime off-grid solar system. (And I'm not even making that up...)

Worked great with the Forney 57637 Lug Crimping Tool (also at Amazon) for making new 2 AWG ground cables for my truck. I used a 12 lb. sledgehammer on the tool and it made a great connection--the starter just about throws the engine out of the car now.

Used this to install 2 more batteries and complete my solar install. Worked great. Was able to solder most connections and had to crimp one and that worked really well also. Used heat shrink on all connections to and from the batteries. All worked well. I ended up using all ten. :)

Really nice heavy duty lugs. There are videos showing people making their own out of copper tubing but for this price, not sure why anyone would mess with that. These are way less than I’ve seen in any hardware or auto parts store and half the time those stores have lugs with holes that are too large. This way you get just what you want. I’ve purchased the lugs for 2 and 4 wire and they fit the wire and crimp on just fine.

Product fits the description and my headline states it all. No reason to not purchase this brand if you are looking for these wire ends. I’ll be adding a range of sizes to my home stock and this company will get my orders! I’ll add a photo in a few days.

Review for bare copper 2/0 awg lugs and 4 awg lugs.The good:Made from decently thick copper tubing (.045" wall for the 2/0 awg and .035" for the 4 awg.) Which means that there is enough material to hold the hex crimp well past the mil spec AND nasa pull test ratings. (Buy a hex crimper and stop using those impact 'dimpler' things.)Closed construction. Once crimped, simply cover with a dual wall adhesive shrink tubing and the cable is protected from corrosion.Nice large pad for good clamping surface.The bad:None really. Will buy again when needed.Addendum: If you are used to working with tweco brand lugs for 2/0 awg cable, there IS a huge size difference between those and the selterm lugs. See photo. Top is tweco. Bottom is selterm. Both perform well though and are just a heads up - not a product quality comparison.

This doesn't fit any of my 1/0 cable properly. Had to strip off many stands of wire off my cable to allow this terminal to fit. Not recommended!

Used 4 gauge ...they were a little lighter than i usually work with, without a lot of material around the edges of the hole. They crimped a bit too easy. I used them for trolling motor batteries that wont have a lot of high amperage. I wouldnt recommend for higher draws like starter cables or in areas subjected to to the elements...not a lot of meat to begin with, any corrosion at all around the lug and they would fail.

Worked as intended. Note: These are super heavy duty copper and need a special crimper. Regular wire crimper won't do the job. If your using these for car audio, these work but are probably not what you are expecting. They are really solid and also quite bulky. Real quality product but understand this isn't just your regular ring terminal like you'd find in the electronics section of your local hardware store.

Reviewing 1 gauge, 5/16" hole.Really nice, thick, beefy copper. The wire end has a flared/rounded tip making it easy to get all those fine strands making up my 1 gauge wire into the connector. Really happy with the amount of copper both in thickness and in the amount making contact for electrical connection. Just bought 10 more to finish my project now that I know these fit the bill, and plan to buy their 1/0 when it comes back in stock and I upgrade some of my wiring as my amp draw increases.

I liked I could order just 2 of them because their for the grounding wires on my Amplifiers which use a 4 Guage wire and the Bolt 🔩 I'm grounding them with is just a tiny bit smaller than ½" perfect for what I need 💯👍🏻
