Seamless tin-plated copper lug for 4/0 AWG stranded copper wire on a 1/2" stud. The closed seamless barrel crimps or solders cleanly onto flexible battery and welding-style cable, and the tin plating resists the green corrosion bare copper develops.

Use it for: battery cables, starter and alternator feeds, battery banks, inverters and main ground straps landing on 1/2" studs, bus bars and terminal posts in vehicles, boats, RVs, solar and battery systems.

Getting the right size: match the wire gauge to the barrel and the ring to your stud. Same 4/0 AWG tinned copper lug for other studs: 3/8". Not sure of your size? Check the ring terminal size chart.

Priced per piece — order any quantity. Finish the joint with adhesive-lined dual wall heat shrink. See all tinned copper lugs.
