Stainless steel screws and washers. Range is great! I will be buying a second pair soon. 5 and the toe was too narrow, so I needed to exchange for a 9. Also, the grates are wide on the bottom, so it was nearly impossible to use a level to make sure it was going to be hanging straight. I suggest using blunt, non pointy tweezers to aid you in your effort and go slow. However for my fussy other half I ordered his usual size 10 and a size 9. The wire seems to be a bit thinner than on previous pairs, which may be the cause of the main issue. Están muy chicas. Was amazed at how small it was when it arrived and almost looks part of how the switch was designed.
