Review on 🔌 40pcs Black and Red 4mm Banana Speaker Wire Cable Screw Plugs with Amplifier Terminal Connector Binding Post Banana Plug Jack Socket Panel/Chassis Mount Connectors Set - Pack of 10 Each by Cindy Plant

These banana plugs are generally of good quality. The metal contact ends are gold plated with threaded holes for set screws for attaching and clamping wires. There are two small grub screws for each of the 20 banana plugs. Plastic insulators are very durable. Unfortunately, they're so firmly attached to the metal structure that it's almost impossible to remove them by hand to gain access to the screw holes. I decided to leave them in place and melt the holes with a soldering iron and trim off the excess. This made it relatively easy to insert small clamping screws. Panel jack, very good quality connectors with tinned solder terminals and two clamping nuts. Female Banana Terminals is threaded so it can be unscrewed to connect the 20 AWG bare wire to the drilled and plated through holes in the base of the contact. I would definitely buy them again.
