Hi, I'm fitting some new door handles to our interior doors which are hollow. However I would like to use bolt-through fixings but I'm struggling to find what I want to use. The bolts/machine screws that I'm searching for are like a machine screw but with a countersunk raised head to look like a wood screw. This bolt (or machine screw) goes through the door and screws into a short threaded insert which has a countersunk rasied head on the end to look like a screw on the other side of the door.
I have no idea what you call this "threaded insert" which adds to the difficulty in me locating this type of fitting.
Does anyone out there know what these are called and does anyone else know where to get them from (in satin nickel).
Any help would be much appreciated.
