Install, extend, or rewire a circuit without hunting down new terminals. These assortments include ring terminals for most small and medium wire gauges and screws. Labels in the lid include our part numbers, so it's easy to replenish your assortment.

Ring terminals encircle the whole the screw shank, so they stay put better than spade and hook terminals when vibrated or pulled. Attach wire with a crimping tool to avoid a damaged barrel and loose 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.

These assortments include the set screw lugs, nuts, and bolts needed for single-phase and three-phase dry-type transformers (transformers that dissipate heat without using liquid).

Set screw lugs are easier to install than compression lugs, and they can be reused because you don't crush the barrel to attach the wire. They don't hold the wire as securely as compression lugs, however—use them when pulling and bending aren't a concern and you need to easily break your connection for maintenance or adjustments.
