DJI Anti-Drop Cover and Screw for ZH3-2D (6-Pack)
MPN's:
Way Over-priced and Poorly Made
I purchased these as replacements to the original screws that just seemed to randomly fall off in-flight. For some reason, I thought I'd give them another try. After installing them and then flying for less than one minute, I landed and saw that 2 of them had already fallen off. I know I tightened them properly, so there's no way they should have come loose (especially on such a short flight). They're designed to be a safety to so that the gimbal doesn't fall from the sky if it ever came loose from the damper bracket.

Expensive to replace so use Locktite
These are pretty pricey for little screws. I would hope there would be an aftermarket version available. I've had 3 fall out from just flying alone. In order to keep them tight, use Loctite Thread Locker BLUE 242. Make sure you only cut a tiny hole since it is a liquid and flows easily. In pinch, you can use zip ties to keep the Zenmuse Gimbal in place.
