Parts Desk Insights

Best Use Case: Ideal when you need a thicker nylon flat washer to cushion and spread force around a 5/8" fastener, such as when tightening components that could be damaged by point loading.

Common Issues: If the washer hole/bore doesn’t match your 5/8" hardware, it may bind or fail to sit flat—double-check that the washer size matches your bolt/stud. Also verify stacking thickness with any washers/gaskets already in the assembly.
