3M M10BCX – Frequently Asked Questions

1) What wire gauges does the 3M Scotchlok butt connector cover?
Two sizes are made: the M14BCX for 16-14 AWG and the M10BCX for 12-10 AWG. Pick by the conductor you are splicing, not by the color of the barrel. For a standard 14 AWG branch circuit conductor use the M14BCX; for 12 AWG or 10 AWG use the M10BCX.
2) Can I use a Scotchlok M14BCX to splice a 12 AWG wire?
No. The M14BCX is built for 16-14 AWG conductors. For 12 AWG, order the M10BCX, which covers 12-10 AWG. Crimping an oversize conductor into an undersize barrel gives you a connection that will not hold mechanically.
3) What is a butt connector actually for, and when should I use a different connector instead?
A butt connector joins two wire ends end to end in a straight in-line splice, so the run continues as one conductor. That is what you want when extending a cable, repairing a cut, or replacing a damaged section. If you need to branch a third wire off an existing run, or bundle several conductors in a box, a butt splice is the wrong shape for the job, use a tap or a multi-conductor connector instead. Scotchlok butt connectors also are not a substitute for a terminal, if the wire lands on a screw or stud you need a ring or fork terminal.
4) What part numbers do I order for Scotchlok butt splices so my stockroom carries both common gauges?
Two line items cover most maintenance work: 3M Scotchlok M14BCX for 16-14 AWG and 3M Scotchlok M10BCX for 12-10 AWG. Those are 3M's own model designations, so they reorder cleanly against a purchase order without a cross-reference.
5) Are these Scotchlok butt connectors suitable for automotive harness repair as well as building wiring?
Yes. 3M lists the Scotchlok butt splice for wire-to-wire splicing and repair, automotive wiring harness repairs, industrial and commercial wiring, panel and equipment wiring maintenance, renovation work, and new construction. Same connector, just match the gauge: 16-14 AWG takes the M14BCX, 12-10 AWG takes the M10BCX.
