While routinely breaking down a test we had a security screw that became stuck, then stripped.
I tried to use a screw extractor, but the center post of the security screw prevented the extractor from biting into the screw, and just spun.
The final solution was to use a Dremel with a diamond bit and it worked, but I couldn't help think what a headache this would be during an install or service call. How often do you see these issues in the field? How do you handle them?
For clarity's sake, the tools used to install and remove the dome were the manufacturer provided security T15 bit and a low power rechargeable electric screw driver that we have used on every other dome tested in the past three years, so we aren't exactly sure how it became so stuck.
