MX Army Type Binding Post Terminal 4mm (MX-424)

A binding post is the no-nonsense way to give a project a permanent, screw-down connection point rather than relying on a jumper wire jammed into a header. This army-type terminal takes its name from the rugged, mil-spec-style knurled cap that's easy to turn even with gloved or wet hands, and it's versatile about what it accepts - loop a bare wire around the post and tighten the cap, slide on a spade lug, or plug straight into the 4mm banana jack opening at the top. That flexibility makes it a natural fit for a bench power supply, a battery test fixture, or any panel where different people will connect to it with whatever cable or lug they happen to have on hand. The all-metal build holds up to years of repeated tightening without the post stripping out.
