6 AWG Copper Ring Terminals

These 3M M6-14R/SK terminals accept 6 AWG wire and mount on a 1/4 inch stud. The brazed-seam copper barrel is bare metal with no insulation sleeve. Each connector is rated for 600 volts and a maximum temperature of 347 degrees Fahrenheit. The pack contains 200 pieces.

Suited for high-current crimp jobs

Electricians and panel builders who need UL-listed and CSA-certified ring lugs for power distribution will find the spec match. The bare barrel leaves no room for heat-shrink or insulated ferrules, so anyone requiring a covered barrel should choose a different style. The single stud size also limits use to 1/4 inch bolts only.

Crimp into a 6 AWG circuit

A proper crimp tool for 6 AWG copper is required to make a gas-tight joint. The 1.42 inch overall length and .47 inch tongue width fit standard bus-bar spacing without modification. Because the terminals are uninsulated, clearance to adjacent phases must be planned during layout. No additional hardware ships in the pack.

Questions about this item

What crimp tool do I need for the 6 AWG copper barrel?

Use a ratchet crimper with a 6 AWG die that matches the brazed-seam copper barrel for a gas-tight joint.

Will the 1/4 in stud fit the existing terminal block on my panel?

The 0.47 in tongue width matches a standard 1/4 in stud, so it seats cleanly on legacy blocks with the same bolt size.

How can I verify the connection is sound after crimping?

Perform a pull test rated for 6 AWG, then check that the barrel shows no cracks and the ring sits flat against the 1/4 in stud.
