Copper Wire Lugs Kit AWG 8/6/4/2

❓Which wire gauges and stud sizes are included?

The 80PCS kit covers AWG 8, 6, 4 and 2 with 5/16- and 3/8-inch holes. The 76PCS kit covers AWG 6, 4, 2 and 1 with the same two hole sizes. The 60PCS kit contains AWG 8, 6 and 4 lugs across #10, 1/4-, 5/16-, 3/8- and selected 1/2-inch holes.

❓Are these lugs tinned?

No tin plating is claimed for these variants. They are bare copper lugs with a pickled surface treatment. Add suitable sealing and corrosion protection when the installation environment requires it.

❓Do I need heat-shrink tubing?

Use adhesive-lined heat-shrink tubing when the crimp needs electrical insulation, strain relief or protection from moisture and contaminants. The 76PCS and 80PCS kits include 40 precut 1/2-inch 3:1 dual-wall tubes; the 60PCS kit does not include tubing.

❓Which crimping tool should I use?

Use a cable-lug crimper whose die range includes the selected AWG size. A light-duty insulated-terminal crimper is not suitable for these heavy copper lugs. Confirm the die mark, complete the crimp and pull-test the cable before energizing the circuit.

❓How to Choose

1. Match the lug barrel to the conductor gauge, not the cable's outer insulation diameter.
2. Match the ring hole to the bolt or stud: #10, 1/4, 5/16, 3/8 or 1/2 inch as listed for the selected kit.
3. Choose the 60PCS kit for more stud-size combinations, the 80PCS kit for AWG 8/6/4/2 with 5/16 and 3/8 inch holes, or the 76PCS kit when AWG 1 is also required.

❓How to Crimp and Protect the Connection

1. Disconnect power, cut the cable square and strip only enough insulation for the conductor to seat fully inside the barrel.
2. Use a cable-lug crimper with a die matched to the cable gauge. Crimp the barrel firmly, then perform a pull test.
3. For kits with tubing, slide the tubing over the joint and heat evenly until it recovers and seals. The 60PCS lug-only kit requires separately purchased tubing when insulation or environmental sealing is needed.
