Go to your nearest Halfrauds & Erm, Um sort of borrow a new screw
No need to take a screwdriver with you, you'll find plenty on the shelves
On a serious note. My local store are as good as gold & have allways honoured the warranty on their tools
The screws on some of my Draper rachets had a habit of becoming loose, a dab of Loctite soon sorted that problem out
