Parts Desk Insights

Best Use Case: Choose this washer when you need a corrosion-resistant 18-8 stainless flat washer with the specific thin .078" thickness and A/N-style outer diameter for your fastener stack-up.

Common Issues: Confirm the outer diameter (OD) and thickness against your assembly requirements—using the wrong OD-style washer can affect clamping area and seating. Also verify the correct washer size before installation to avoid misalignment with the bolt/shaft.
