M3 Thumb Screw for D-Sub Backshells
The Molex 1731120402 is a jackscrew / thumb screw accessory from the FRS, FCT series, designed for use with D-sub backshells. It carries an M3 thread and measures 43.5 mm in length. This is the hardware that secures the backshell to the D-sub connector body — the thread size and length must match the backshell's threaded insert and the panel thickness.
