The machine screws I received were not what I had needed, although they were of excellent quality. As a novice in purchasing specialty screws, I decided to ask for help. I sent an email description of what I needed and Scott from FMW Fasteners promptly responded. After an exchange of another email Scott knew exactly what I needed and shipped them to me. The service I received was very impressive even though this was my first order from FMW and was for only 25 screws. Thanks a lot, Scott.
