SELTERM10pcs 4 AWG-5/16 Stud Tinned Copper Wire Lugs, Heavy Duty Battery Cable Ends,4 Guage Ring Terminals, UL Battery Lugs Marine Grade Copper Eyelets Electrical Battery Terminal Connectors

I've been an electrician for 35 years and have used a lot of crimp connectors. Tinned copper is the way to go. These connectors are well made and work perfectly. Just a note to the average user, you need a large crimp tool to secure these. If you think you can do it with a small hand-held crisper, you can't. That's true of any crimp connector of this size.

Used it to terminate winch cables to my battery. I didn't have the correct crimper, but instead I clamped the ring terminal in a vise, put a bunch of solder into the cup end, heated it up real hot with a propane torch and stuck the stripped copper end of the cable into the molten solder. Covered with some adhesive backed heat shrink and works great!

An Online chart referred 2 AWG = 0.258 inch bare diameter. It did not work for the 1/4 inch stranded wire (with 3/8 inch insulation) after crimping. Lug opening = 21/64 inch (0.3281 inch) drill bit. The opening is too great to compress down to slightly below 1/4 inch (0.250 inch) to tighten against the wiring, which leaves excess dog ears. Recommend seller to specify the initial opening, which can compress down to the min. size. Will have to order smaller size lugs to see if this will correct the problem. Used a YQK-300 Hydraulic Crimping Tool with die #25.

we have a MK4 Jetta that had the dreaded "fuse box meltdown", after attempting a new box with cleaning up the oxidized cable best we could only to have it melt again a month later we opted to spring for a hydraulic hex crimper, 4ga copper welding wire and two sizes of Selterm tinned copper wire lugs (one for each end of the new alternator cable we we assembled to resolve our problem)the items arrived quickly and look to be of quality expected. all 10 lugs look to be well made with no inconsistencies/flaws, and our test cable and actual cable worked well.car is fixed, wife is happy.

I'm up to my ears in a boat rewiring project. I needed a number of battery/power cables of specific lengths, and was growing increasingly horrified by how much custom cables actually cost. So I decided to make my own custom cables - I got some 4GA cable, assorted appropriately-sized crimps (these parts), and a crimper/cutter tool combination, and then got busy.In the end, I was able to make a half-dozen custom-length cables for about half the cost of "professionally made" versions. It helped that I was a professional cable/harness maker in a previous life - I do know what I'm doing here. I'm also an engineer by training and profession, as well as a big MacGuyver fan - I take some small amount of pride in being able to get the job done, no matter what it is.There is certainly a trick to getting good big-cable crimps from inexpensive tools and parts, but it CAN be done. It just takes practice, patience, and a learning curve.

As advertised, worked great! I think the 2/0 wire I was using may have been slightly undersized as I found I received better results if I used the next size down die for the crimper. These terminals would pinch in the smaller die, but that is not a fault of the terminals. So far my connections have looked great and have held up well...granted time will tell.

This product was advertised along with my original purchase of number for cable as a customer suggestion. Do you original kit that I bought was short for eyelets so I bought this kit. It is advertised as for Gage , It’s not even close I had to remove a portion of the copper winding to get these over the actual cable as well as the whole size why is half the size of the original order. For something so small you’re better to go to a box store pay a few pennies extra and get an accurate product and description

Seems to work as advertised. At first had issues with it showing different values for voltage with and without a load. The voltage actually went up with load but according to my meter the "unloaded" voltage was correct. This was on a test setup. When installed in our off grid cabin using more or less the same setup and wiring it seems to read fine. Have no idea why things changed but all is good. Will be remote mounting the display with a 30-50' wire when everything is finally in place so we'll see how it works then. The only issue I thought could be improved is there is no mounting for the shunt so you'll have to make one to isolate it. I'll update if there are any issues with the extension or otherwise.

Ordered M6 but very loose on stud. So when measured, it was 7mm dia. Not M6. No use to me.

Good

Arrived as advertised

I bought 6 gauge terminal lugs to hook up a 10 kW electrical heater. Using a large crimp tool it crimped on just fine. I always pull test new crimps to check them. With the lug in a vice I pulled on the wire and was able to walk it back out. I retried using one size down on the crimp tool and it now held satisfactorily. These lugs are thinner wall than I think is standard so when crimping the tool bottoms out and only squeezes so much. I was able to make them work but I suspect a higher quality lug has thicker walls and would retain the wire more tightly.

These Copper Cable Lugs are Marine Grade (Tin Plated) with 5/16 " Ring and are made to receive #2 AWG Welding Cable. My #2 Welding Cable enters the Lugs nicely. Embossed on the Lugs "M2-5/16-UL". Exactly 25 units in the bag. Good quality and heavy duty Lugs. Made in India. Paid $26.82 (28.82 -2.00 Coupon) for the 25-pack. Rating: 5-Star.
