This is a heavy-duty M4 internal thread U-shaped SMT surface mount soldering terminal, constructed from solid 1.0mm thick high-grade brass material for superior conductivity.

It supports M4 standard screw locking, with an outstanding 45A high current carrying capacity. The dedicated dual-foot SMT 贴片 design fully supports automatic high-speed pick-and-place machines and standard reflow soldering processes, completely compatible with modern SMT mass production, no manual operation needed.

One-piece precision stamped brass construction guarantees excellent solderability, ultra-strong welding retention, zero cold joint risk, great vibration resistance and permanent anti-loosening performance. Perfect for high power PCB boards, industrial control drivers, power supply modules, new energy equipment and heavy load electrical connection & grounding applications.
