I recently bought an old chandalier. The candle(light) holders are threaded but a standard M10x1.0 nut would not fit. I bought a pitch gauge and they measure 0.9mm pitch. I cant find any refere nce to M10 x 0.9 pitch, nuts, tap or dies. Is this a size that may have been produced at some time?
Where might I found some nuts?
Should point out it is most likely an Italian chanadalier.
