These prevent pullout better than other compression lugs, and they give you more options for attaching the wire. To attach with solder, heat the enclosed solder onto your stranded wire. This bonds the wire to the lug for a secure hold and a continuous, ultra-conductive metallic connection. If sharp bends and tugs aren't a concern, you can skip the soldering and use a compression tool to squeeze the barrel tightly and evenly onto the wire. Compression lugs are a step up from set screw lugs when you need a physically strong connection, though set screw lugs attach to even larger wire.

Solder these welding lugs in place, or use a crimping tool (not included) for a secure connection.

Keep a variety of welding lug sizes on hand. Either solder these welding lugs into place, or use a hammer-on crimper (not included) for a secure connection.
