Parts Desk Insights

Best Use Case: Ideal when your assembly calls for an M12 flat washer with a 24 mm OD and 2.5 mm thickness to achieve the specified bearing area under the bolt head or nut.

Common Issues: Confirm you’re matching both the M12 size and the 2.5 mm thickness; using the wrong washer thickness or diameter can change clamp load and bearing contact. Also verify you’re using the correct stainless hardware spec for your environment.
