9/16 中型開口彈簧墊圈 | 鋼鍍鋅 (250 / 包裝)

The zinc plating on these washers looks clean and uniform, so they won’t rust out in my garage. I’ve got a 250-count pack for reassembling my lawnmower deck, and they hold tight under the vibration without any loosening.

I ran out of the old ones halfway through rebuilding a trailer, and these matched the #9 size perfectly. The zinc coating gives them a clean, even look and should hold up fine in the weather.

Installed these on my mower deck bolts last week and everything stayed tight even on a bumpy lawn. The steel feels sturdy and the zinc coating should help resist rust around grass clippings.
