MX 4mm Banana Male Plug Connector Solderable Type Beryllium Copper (MX-1399)

Soldering a wire directly into a connector gives a permanent, low-resistance joint that some builders prefer over a crimp or screw terminal, especially for a lead that's being hand-built rather than assembled at volume. This plug's solderable terminal accepts a stripped and tinned wire end cleanly, and the beryllium copper contact body holds up to the repeated plug-unplug cycling a banana connector sees on a bench far better than standard brass would. A solid choice for anyone building their own precision test leads who wants full control over the termination quality rather than relying on a pre-crimped joint.
