iGreely10pcs 8 Guage 5/16" Wire Lugs Ring Terminal Connectors Ends 8 AWG Heavy Duty Tinned Copper for Battery Cable Lug Wire Electrical Eyelets with 10pcs 3:1 Dual Wall Adhesive Heat Shrink

They are great quality. I returned for a smaller guage with no problems.

These lugs are perfectly sized for 1/0 copper. As I do not have a crimper that size, I used a torch and solder. Wadded up some thin rosin core and stuffed it into the bottom. I wish they were all 5/16", it is easier to drill the hole than it is to fill it with solder and drill. The price for 10 lugs with shrink tubes included delivered is the same price as 2 in my local store.

Liked how easy it soldered to the wires, used on a fishing boat. Would purchase again when needed!

they should make more in different colors too

As you can see by the photo, there is no open end near the ring. That's not necessarily a bad thing, as you can still solder wire to it just fine. You shouldn't have any problems crimping these either.They are quite strong although I'm not entirely happy with the large ring hole diameter (13/32 or 10.32mm) with an edge of 5/64 on the far side as there isn't a whole lot of metal thickness (3/64) to conduct at higher amperage. It should just be barely enough to work with 8 AWG wire, which is what these are made for. I would make sure the entire ring is making solid contact with the post it is connected to and screwed down on.Supplied shrink tubing is adequate and long enough to provide ample coverage and protection.

This was as good as any other stuff. Used on wiring for solar install.

These 1/0 gauge wire lugs are well made of a heavy copper that is plated for extra corrosion protection. The supplied shrink tube is thick walled with a sealant that melts to form a waterproof seal. This kit worked great for the custom battery leads built for the project. Thanks and God Bless

Very good quality
