Just a habit of working on aircraft. The robots are vibration machines, so any little advantage to screws backing-out I will take. We have quite a few fastener stores in the area, so access to fine thread fasteners is not an issue.
That being said, we haven't used a 1/4" fastener on the robot in quite sometime - maybe a COTS component that required. We have used #10 rivet nuts in 1/4" holes in the past in the KOP frames.
