4 AWG Nylon Ring Terminal
This 3M ring terminal connects 4 AWG copper wire to a 1/2 inch stud using a crimp termination. The nylon insulation is rated for 600 V and temperatures up to 221 degrees F. It carries CSA certification and UL listing for code-compliant installations. The pack contains 200 pieces for volume wiring work.
Crimp installation with brazed seam
A proper crimp tool sized for 4 AWG is required to compress the brazed seam barrel onto the conductor. The .68 inch tongue width must align with the stud to avoid mechanical stress on the connection. Under-crimping creates high resistance; over-crimping can fracture the barrel. Inspect every crimp for full conductor insertion before energising the circuit.
600 V capacity with thermal headroom
The terminal handles 600 V continuous voltage within the 221 degree F temperature limit. The overall length of 1.74 inches fits standard lug spacing in panels and equipment. Yellow colour coding identifies the 4 AWG wire range at a glance. It is not suited for wire gauges outside 4 AWG or for stud sizes other than 1/2 inch.

Questions about this item
How can I verify the crimp connection is secure after installing the 4 AWG wire into the ring terminal?
After crimping, perform a pull test on the wire; the brazed seam and copper construction are rated for 600 V and up to 221 °F, so a firm hold with no wire movement indicates a proper connection.
What comes in the package and do I need to buy a crimping tool separately?
The package contains 200 yellow nylon-insulated ring terminals with a 1/2 in stud size and 0.68 in tongue width; a compatible crimping tool for 4 AWG wire is not included and must be purchased separately.
Which version should I choose if I need a yellow nylon terminal for 4 AWG wire and a half-inch stud?
This part is the 4 AWG yellow nylon ring terminal with a 1/2 in stud, 1.74 in overall length, and CSA/UL certifications; it matches those exact specifications.
