18 AWG Fork Terminal for #6 Stud

This 3M vinyl-insulated fork terminal accepts 18 AWG wire and fits a #6 stud. It is CSA certified and UL listed for electrical connections up to 600 V. The butted-seam barrel with funnel entry supports reliable crimp termination. It suits automotive, appliance and general-purpose wiring tasks.

Vinyl insulation and butted-seam barrel

Red vinyl insulation provides a maximum operating temperature of 221 Degrees F and a voltage rating of 1,000 V. The 0.25 in barrel length and funnel-style entry ease wire insertion before crimping. Compatible crimp tools include manufacturer models TH-440, TH-450 and TR-490 for consistent terminations.

Verify wire gauge, stud size and crimp tooling

Confirm the circuit uses 18 AWG conductors and a #6 mounting stud before ordering. Ensure a suitable crimp tool matched to the butted-seam barrel is available for installation. Check that the 600 V rating meets the application's voltage requirements.

Questions about this item

Does the vinyl insulation on this 18 AWG fork terminal degrade at the 221 °F maximum operating temperature?

The vinyl insulation is rated for continuous operation up to 221 °F; above that temperature the material can soften and lose dielectric strength, so the terminal should be replaced if the wiring environment regularly exceeds that limit.

At 600 V, does the butted seam become the current-carrying bottleneck before the copper barrel does?

The butted-seam barrel is the narrowest cross-section in the crimp path, so under sustained 600 V loads the seam area will reach its thermal limit before the solid copper barrel does.

How warm does the #6 stud connection get when the terminal runs at its 600 V rating all day?

With a 0.25 in barrel and funnel entry, the crimp joint typically runs only a few degrees above ambient at rated current; the 221 °F insulation limit provides a wide margin before heat becomes a concern.
