Parts Desk Insights
Best Use Case: Use when assembling or reassembling bolted marine hardware where vibration can gradually loosen standard fasteners.
Common Issues: If the washer doesn’t seat flat, confirm the bolt length/protrusion and that the mating surface is clean and not deformed. Avoid mixing washer sizes—use the correct M12 size for best clamping performance.
