01-0146-001 is a threaded coupling nut designed for Binder series 423/425/723 connectors. It features an M18x0.75 metric thread with a width across flat (SW) of 20 mm, enabling secure hand-tight connection at approximately 60 cNm torque. The component is manufactured from CuZn39 Pb3 brass material with a minimum tensile strength of 430 MPa, finished with a Cu/Ni/4 half-hard surface treatment per DIN 50968. Weighing 1.98 grams, this coupling nut is designed to prevent accidental disconnection of cable connectors from device connectors, making it essential for reliable connector assembly in industrial and electronic applications.
