If you do snap em off at pre marked sections (these sections have no thread) screw them together and undo a couple of times first before poking through door as sometimes the very end of the thread can be damaged by snapping them. If you hang a door wrong then you end up fitting the handle to the side that's hollow and that's what you have found. I still have the parts from the original handle, including the latch, which looks to me like a 'bolt through tubular latch' - would it still need changing?

How to use: Drill a hole through the door leaf, place door handle on the door to match up with the hole drilled and push the screw trough the door handle, door leaf the handle on the other side.I'm happy to put on a different shape handle and paint the door to cover any damage but what can use to fill those holes that I can drill again and put a new handle on. M3 no snap off screw – can be cut with electrician pliers Both the sleeve and the screw has a slotted head. With the handle bolts that Wayners suggested, these are drilled completely through the door and bolt the two handles together. Given the damage to the 'wood' of the door, would it hold without doing something to repair or patch underneath the rose? I'm happy to have a go at DIY but I've never done anything like this before so apologies if my questions seem frustrating.

These screws with sleeves are used to replace existing or damaged screws that attaches two handles together. mm Note: M3 screws are not security screws and therefore are not suitable for external door handles.
