I have purchased a number of micro-motor pairs for testing a robotic creation that I have under development.
The problem that I have is the hardware. The brass colored gear housings are coming loose and the long screws fail to re-tighten.
Today, the robot tilted to one side and landed back on it’s wheels and the housing came off.
Is it possible to get a slightly longer screw for these motors?
Are there any other options for repair? Like super-glue 
or something?
What is the next step up for durable motors…
