As with everything else, screws are now being made in China and the quality is not what we used to get in screws even just a few years ago. I have started making my own screws, it is not that hard to do. I have just accepted that we will never get back to a quality that we will ever be able to buy a decent screw again so I bought a set of dies and turn my own blanks. Wood screws I also file by hand, again not that hard to do. I have found that making my own screws gives me the quality that I demand in the rest of my build.
I started making screws when I started doing restoration work on antique guns. It just did not seem right to replace a missing or broken handmade screw with a modern store bought screw.
