I would recommend terminating it to the same stud you use for earth ground with a ground wire on the chassis. |

It's quite possible that earth point could be tens of centimeters away and do not provide good high frequency path. And it's purpose is safety, not signal ground. |

If possible otherwise another thread mount can be used. How do you typically bond shield to chassis if not through a bulkhead mount or thread protrusion? You can't really mount a faston receptacle on the chassis directly, you need to use a screw, you might as well minimize the amount of interconnects since the screw can be unthreaded. If manufactured you would rather insert a threaded rod into the chassis rather then a threaded hole since its more material efficient and you don't need to use very short screws that are not common or hold weird things in your inventory since you can just use a standard nut and star washer. Unless you mount to a internal wall then you can use a threaded hole since it does not really matter the bolt is not flush with the other side of the internal wall so long its not an obstruction. but IMO its generally kinda shit because well its a screw thats half way sticking out of something lol |

that's what I saw typically done on harnesses that connected various electromechanical devices and control/power/communication boards in a single chassis, but it was not a point to point connection more like a harness for an entire device with many many systems. I imagined it similar to basically running all the wires through a shielded raceway but cheaper. |
