Hi All, Made a few slip ups when I was fitting door handle on to new door, and it's come back to bite me, as someone's enthusiastic pulling of the handle has made it eventually come loose. Can't screw in deeper as the metal box of the lock part is there, but now the screws have no grip. Wondered about filling with a strong glue and screws into that, but then it's never coming off I imagine. But can't think of much else? Cheers for any suggestions and hope everyone's keeping well.
