This is the place where you can find any little 'part' that nobody else has. They have everything. We looked everywhere for a little wheel to fix our sliding shower door. Nobody carried it. Ace Hardware said you can't get it anymore, replace the doors. Guess what? McMaster had it. If you need something you can't find anywhere this is the place. Expensive but cheaper than replacing everything.
