Parts Desk Insights
Best Use Case: Use this flat washer when you want a larger bearing surface to help spread load and protect the mating material around the fastener hole.
Common Issues: If the washer won’t sit flat, re-check the mating surfaces and ensure the correct washer size (3/8" for the fastener) and thickness (.062") are being used for the intended stack height.
