I think this fits into this thread, I have recently had to deal with someone breaking into my backyard to try and steal my motorbike. Among the other things, I'm going to round all the screws keeping the gate hinges and fixtures in place. i tried a drill but it wasn't that successful I tried a posi drive bit that rounding the outside very well but not the inside so you can still remove the screw with a screw driver. can anyone suggest anything, please? I'm not flush with money so I'm looking to do this as cheap as possible.
