Uxcell 20mm O.D. 1mm Thick Nylon Flat Washers for M12 Screw Bolt, 50 Count

I think these washers are great to have in your tool box. They come in handy when a screw needs extra space or you dont want the screw or nail hitting the object. I needed some ectra cushion you could say between the screw and a dresser surface, I used about 4 of them and it worked great. They are small like a dime and very thin and plastic. Breakable if you bend it in half but sturdy otherwise. I also used one when I hammered a nail into the wall, I put the washer on the wall and then the nail just so I didnt go thru all the way with the nail. All in all these are great to have for odds and ends. I actually found multiple uses for them.
