I'm after some grub screws for door handles, they hold the handle still on the square threaded bar. The door handles are 100 or so years old though, and the current ones are made of brass, with what's apparently a 7/32" thread, no head as such, more like a bit of threaded bar with a rounded top and a slot cut into the top.
Has anyone any idea where I can find some more? None of the local hardware shops have them or any clue of where they can be found, and I'm getting a bit sick of not being able to open any doors.
