Top notch quality! You can weld, crimp and heat shrink with these all day long! More than enough for the price, and extra for your next project!

Great product. Won't fit real 0 gauge wire though. I had to cut a couple strands off. Very durable and flared ends!

Excellent battery/cable ends. The quality of these cable ends is obvious. Worth every cent. They also crimp extremely well. Spend the extra few cents and get the WindyNation brand, you won't regret it.

I purchased these 5/16 as well some with 3/8" hole fittings, I used the 3/8" on the battery terminals and these fit nearly everything else, The starter, the new Fuse link I added, the alternator (with some filing down), I stuffed some solder in the fittings, wrapped the wire with some more solder, slipped on some shrink tubing, shoved the 2 ga wire in fitting all the way to the sheeting, I then used my hydraulic crimpers (which I loved) and crimped the connectors on, I then too a small butane torch and melted the solder, after it cooled down I slid the shrink wrap over it and heated to make a nice clean connection - These fittings worked perfect !!!!!

Best price per terminal ratio I found. The quality of the lugs are nice and are as better quality then the ones from my local auto stores and ac Delco store. Theirs are dirty and not as shiny.

Not much to say. They're true copper, thick enough to get a quality hammer crimp even on heavy 7-strand wire. Good connection and aren't corroding at all even months later. Was capable of drilling one out to take a 3/8" lug without the bit grabbing it and turning it into a pretzel, which also says something.
