Parts Desk Insights
Best Use Case: Use as a standard flat washer under an M8 fastener head or nut to spread load and reduce wear on the installation surface.
Common Issues: If the OD or thickness doesn’t match your original washer, clamping load and surface protection may be reduced—re-check the washer size (OD 16 mm, thickness 1.6 mm) before installing. Also confirm you’re using an 18-8 stainless washer when working on stainless hardware to maintain compatible corrosion performance.
