Gold-plated copper banana plug with screw-lock termination for 4 mm speaker cable

  • Gold-plated copper ensures low-resistance signal transfer
  • 4 mm plug diameter fits standard speaker terminals
  • 5 mm open hole accepts thick cable cores
  • Screw-lock design secures wires without soldering
  • Colour-coded insulation simplifies positive and negative identification

Gold-Plated 4 mm Banana Plug

This gold-plated banana plug is a male hybrid connector built from pure copper with colour-coded plastic insulation. It accepts a 4 mm plug and features an 18.5 mm open hole for secure termination. The screw-locking design removes the need for soldering, making it suited to speaker and amplifier wiring jobs.

Replacing Bare-Wire or Soldered Ends

The connector replaces stripped wire or soldered terminations that can loosen or oxidise over time. The jump is worth it when you want a repeatable, tool-free connection that resists corrosion and simplifies future re-termination. It is not for installations that require a female socket or a different plug diameter.

Screw-Lock Installation Without Soldering

Installation uses the built-in screw terminals so no soldering iron is required. Strip the cable, insert it into the 18.5 mm opening, and tighten the screws for a firm hold. Common issues include over-tightening the screws which can damage fine strands, or using wire thicker than the 4 mm entry which prevents a proper seat.

Questions about this item

What size binding post will the 4 mm plug fit?

The plug diameter is 4 mm / .16 in so it matches standard 4 mm binding posts.

How do you secure the wire without soldering?

Strip the cable, insert it into the 18.5 mm / .73 in open hole, then tighten the set screws to lock the conductor.

When should the connector be replaced?

Replace it if the gold plating wears through, the copper shows corrosion, or the screw threads strip and no longer clamp the wire.
