Heavy Duty Seamless Corrosion Resistant Tin Plated Copper Lugs combine pure copper construction with a seamless pad to provide the ultimate performance in strength, conductivity and corrosion resistance. The lug design and features a flared and chamfered barrel to facilitate cable insertion. These lugs are sized and designed to work with flexibly stranded copper wire and cable such as welding cable, marine battery cable, UL Listed battery cables, SAE battery cables, entertainment cable, diesel locomotive cable, and other similar flexible cables.
The tin plating provides corrosion resistance which is superior to bare copper lugs. Utilities, telecom and other industries using high amperage connections all use tin plated lugs and terminals for power connections.
The hole sizes on the lugs are sized to fit the bolt of the same size so a 5/16 hole lug will fit a 5/16 inch bolt etc. The 5/16 lugs will also fit M8 metric as will the 3/8 lugs fit the M10 size metric bolts.
Also keep in mind the sizes of cables go from smaller to larger as so:
8 AWG Smaller6 AWG4 AWG2 AWG1 AWG1/0 AWG (0 Gauge)2/0 AWG (00 Gauge)3/0 AWG (000 Gauge )4/0 AWG (0000 Gauge) Larger
