8mm內徑 x 38mm外徑 鋼製墊圈

Exactly the right outer diameter for the grommet I needed to fix. The hole in the center fits my bolt snugly, no wobble at all.

The steel feels solid and heavy-duty, not flimsy like some cheaper hardware I've used. I needed a few extras for a repair job, and the 38mm outer diameter was exactly as specified. Clean edges too, no burrs to file down.

This washer fit perfectly through the bolt I had, and the steel feels solid enough to hold up under tension. No rust or bending so far, which is exactly what I needed for a quick fix.
