Fork Terminal for #10 Stud

This fork terminal accepts wire from 22 to 18 AWG and fits a #10 stud. It is built for electrical and industrial wiring tasks that require a crimp connection. The nylon insulation is rated for 600 V and meets UL and CSA standards. It suits installers who need a reliable tin-plated copper contact.

Thermal and Electrical Ratings

The terminal operates from -40 °F to 221 °F without derating. Nylon insulation resists heat and maintains dielectric strength at the full 600 V rating. The butted seam and crimp termination keep resistance low under normal load. No active cooling or derating is required for typical panel or harness use.

Wire Range Decides Fit

The single specification that determines compatibility is the 22 to 18 AWG wire range. Conductors outside this range will not crimp securely in the barrel. Buyers who need to terminate larger or smaller gauge wire must select a different terminal size.

Questions about this item

How do I crimp the 3M MNG18-10FBX fork terminal onto 18 AWG wire without damaging the nylon insulation?

Strip the wire to match the 44 in barrel length, insert fully into the copper barrel, and use a ratcheting crimp tool sized for 22–18 AWG; the butted seam requires even pressure all round so the nylon sleeve does not crack at the 221 °F rating limit.

Will the tin-plated copper contact need re-tinning or replacement after years in a 600 V automotive circuit?

The tin finish on the copper barrel resists oxidation under normal conditions; inspect for discolouration or high resistance at each service interval, but no scheduled re-tinning is required while the terminal stays within the -40 °F to 221 °F operating range.

At what current does the #10 stud connection become the thermal bottleneck during continuous 600 V load?

The limiting factor is the 18 AWG wire ampacity, not the terminal; the copper barrel and #10 stud are rated for the full 600 V insulation withstand, so sustained heating will trip the wire’s own capacity before the fork terminal reaches its 221 °F maximum.
