Tinned copper cable lugs feature pure electrolytic copper, tinned to prevent corrosion. Many sizes to fit various AWG cables and various stud hole sizes. These heavy duty ring terminal lugs are UL listed and popular for use on flexible stranded cables such as marine battery cable and welding cable. Sizes available from 8 AWG up to 4/0 AWG and uses vary from batteries, starters, alternators, power inverters and many other items for marine or land use. While these are marine grade due to their design, that added quality goes a long way in other environments.
