6 AWG Nylon Ring Terminals

These 3M MN6-516RK terminals accept 6 AWG wire and fit a 5/16 in stud. The nylon insulation is rated to 221 °F and 600 V. Each crimp lug uses brazed-seam copper with a blue colour code. The pack contains 200 pieces.

Suited for high-current automotive

Installers running 6 AWG circuits to battery posts, bus bars or starter terminals will find the 5/16 in stud size a direct match. The blue insulation identifies the wire gauge at a glance. Buyers needing a smaller or larger stud, a different wire gauge or a non-insulated lug should choose another part.

Capacity and headroom for 6 AWG loads

The copper barrel and brazed seam handle continuous current within the 600 V, 221 °F rating. The .63 in tongue width fits standard 5/16 in hardware without crowding. The 1.58 in overall length leaves room for heat-shrink or tape. Circuits exceeding 6 AWG or requiring higher temperature ratings are beyond this terminal's scope.

Questions about this item

What wire gauge must I already have to use these 6 AWG ring terminals?

These terminals accept 6 AWG copper wire, so you must already have that exact gauge for a proper crimp.

Will the 5/16 inch stud size fit the existing bolts on my older battery posts?

The 5/16 inch stud size matches many standard automotive battery bolts; verify your post diameter before crimping.

How can I confirm the crimp is secure after installing the 200 terminals?

Perform a pull test on each connection; the brazed seam and nylon insulation should hold firm up to the 600 V rating.
