3M terminals and connectors

Reliable electrical connections without soldering.

3M solderless terminals and connectors deliver quick, secure electrical connections for automotive, marine and industrial work.

3M insulated ring, spade, fork and butt terminals

Fast, clean installation

Make connections quickly with a crimping tool. Positive wire insertion helps prevent strand hang-ups.

Reliable under stress

Built to handle mechanical stress, vibration and tension while maintaining consistent electrical performance.

Ready for harsh conditions

Resists corrosion, temperature extremes and weather exposure in demanding work environments.

Flexible and serviceable

Disconnect and reconnect for repairs, upgrades and design changes, with terminal styles for different wiring needs.

Efficient for the job

Faster installation means less labor, with no heat, flux or soldering equipment needed.

Protection and consistency

Insulated options help protect against shorts, while proper crimping creates repeatable connections.
