This socket is not all metal as presented in the picture, but it's a gold plastic sleeve. In most cases this may work, except that I had purposely chosen this model because I had a metal sleeve to suit the thread of an ancient lamp incompatible with modern threads. Obviously redo thread in the same hard plastic is impossible. This particular case says my lower rating. NB: For those seeking a true metal sleeve, I have found one similar to the photo, the BHV.
