Metric DIN 9021B A2 (18-8) Stainless Steel Fender Flat Washers

When your fastening application requires maximum surface coverage and dependable corrosion resistance, the Metric DIN 9021B A2 Stainless Steel Fender Flat Washer delivers superior performance. Engineered with an oversized outside diameter, this metric fender washer distributes clamping force over a larger area, reducing the risk of pull-through, cracking, or surface damage—especially on thin or soft materials.

Oversized Design for Maximum Load Distribution

DIN 9021B Large Outside Diameter

Manufactured to DIN 9021B specifications, these washers feature a significantly wider outer diameter compared to standard DIN 125 washers. The expanded bearing surface improves load distribution, enhances joint stability, and reinforces oversized or slotted holes in panels and assemblies.

Ideal for Soft and Thin Materials

The broad surface area makes DIN 9021B fender washers perfect for fastening into plastic, fiberglass, sheet metal, wood, and composite materials. They are commonly used in panel mounting, enclosure fabrication, insulation systems, and structural reinforcement where additional support is critical.

A2 (18-8) Stainless Steel for Corrosion Resistance

Crafted from A2 stainless steel (18% chromium, 8% nickel), these washers offer excellent resistance to rust, moisture, and mild chemical exposure. This corrosion-resistant composition makes them ideal for indoor and outdoor use in automotive, construction, marine, HVAC, and industrial environments.
