I have plenty of extra I can use in my stash, but seeing as how the floodlights only come with the exact number you need, this is sort of a problem. One screw is filled in with metal at the head where it’s supposed to be punched out.
Sorry about this experience. We’ll send it to the team to review. In the meantime, if you give our support team a call they would be more than happy to assist with this!
