Unless you tin the conductors first, these nuts tend to break strands, have little/no resistance to vibration, and unless wrapped with tape, don't protect the conductors from exposure to moisture. You have to be "nuts" to use them for anything smaller than 14 ga inside "house" wiring.Wire nuts.
For light gauge interior DC wiring, stakons crimped to the conductors work. For exterior wiring, use professional type crimped pin connectors, automotive ID connectors or soldering with added insulation such as shrink tubing or 33 tape.
