Hi Veera,

Our SDK currently is optimized for objects that have a lot of texture and structure. Shiny Objects like screws are not the opimal targets for the SDK at the moment, meaning there is no guarantee that the object is recognized and tracked properly under different conditions / scenarios. 

With difficult objects, we definitely recommend to test the reco / tracking under real conditions to check the baviour.  You can find details and Tips / Tricks for Object Targets here:

Thx and greetings
