Parts Desk Insights
Best Use Case: Use this washer anywhere you need a stainless flat washer that matches the 5/16 in. hardware size with a 0.062 in. thickness and 9/16 in. OD—commonly under bolt heads or nuts to distribute load.
Common Issues: Double-check that the washer’s OD and thickness match the clearance and stack height of your specific mount. If you’re replacing older washers, confirm you’re not mixing standard washer styles with A/N-style outside diameter requirements.
