My daughter bought a house in Dunedin that was built mid-30s. She's renovating it, but wants to keep all of the existing door furniture. Some of the screw\bolts that anchor the handles to the square spindles are missing. (So the handles fall off :-))
Anyone know what the thread type is (ie, whitworth, bsw) or where I might find some replacements?
She bought some 12mm x 3\16 from M10 but the thread is way too coarse.
Advice please :-)
