Our take on the Gold Plated 4mm Black Binding Post

A single 4mm binding post with a gold-plated body, a color-coded ring and screw termination. It handles up to 15A and fits panels up to 6.3mm thick through a 6mm cut-out, with an M4 thread for wire. It suits speaker and amplifier builds, test rigs and DIY audio projects. Compared with plastic-bodied posts it conducts better and resists corrosion, but it is a single terminal, so a pair or a full set costs more than a basic binding post pack.

Best forSpeaker and amplifier buildsTest benches and DIY electronicsReplacing a worn or corroded terminalBuilders who want gold-plated contacts
Pros
  • Gold plating resists corrosion and keeps contact resistance low
  • 15A rating covers most speaker and low-power amplifier wiring
  • Color-coded ring helps keep polarity straight
  • Screw termination and M4 thread take bare wire or spade lugs
  • Fits panels up to 6.3mm through a standard 6mm cut-out
Cons
  • Sold as a single post, so a stereo pair needs two
  • Gold plating wears through with repeated tightening
  • Only 15A, so not for high-current power runs
  • 26mm length may be tight in shallow enclosures

Questions and answers

Is this one binding post or a pair?
It is a single black binding post. For a speaker pair you need two, and for red and black polarity coding you need one of each color.
What wire and connectors fit it?
The M4 thread takes bare wire, spade lugs and banana plugs. The 4mm size is the standard banana plug diameter.
What panel hole does it need?
It needs a 6mm cut-out and fits panels up to 6.3mm thick. Thicker panels will not clamp properly.
Can it handle a power amplifier output?
It is rated at 15A, which is fine for most speaker-level outputs. It is not intended for mains wiring or high-current power distribution.
Is the gold plating real gold?
It is a thin gold plating over the base metal, used for corrosion resistance and contact quality, not a solid gold body.
How is it mounted?
It passes through the panel cut-out and tightens with a nut behind the panel. The screw termination then holds the wire.
