80PCS Copper Wire Lugs Kit AWG 8/6/4/2

❓Does this 80PCS copper wire lugs kit include a crimper?

No. The kit contains 40 copper lugs and 40 heat-shrink tubes; a crimping tool must be purchased separately.

❓Which stud sizes are included?

Each AWG size includes both 5/16-inch and 3/8-inch ring-hole options, with five lugs per AWG-and-stud-size combination.

❓How do I select the correct copper lug?

Match both the conductor gauge and the connection stud. The barrel must match 8, 6, 4, or 2 AWG, and the ring must match a 5/16-inch or 3/8-inch stud.

❓What heat-shrink tubing is included?

The box includes 20 red and 20 black dual-wall tubes. Each tube is 1/2 inch × 45 mm with a 3:1 shrink ratio.

❓How to Choose

• Match the lug barrel to the conductor: 8, 6, 4, or 2 AWG.
• Measure the bolt or stud and choose either 5/16 inch or 3/8 inch.
• Use a heavy-duty cable lug crimper with a die sized for the selected AWG.
• Use the included heat-shrink tube when insulation, strain relief, and color identification are required.

❓How to Crimp and Seal

1. Disconnect power and cut the cable cleanly.
2. Slide the selected heat-shrink tube onto the cable, then strip only enough insulation for the lug barrel.
3. Insert the conductor fully and crimp with the correct heavy-duty die.
4. Inspect and pull-test the crimp.
5. Center the tubing over the barrel and cable insulation, then heat evenly until fully recovered and sealed.
