Product Description
Metric A2 Stainless Steel Form G Flat Washers DIN 9021
Metric A2 stainless steel Form G flat washers provide a larger bearing surface than standard Form A washers. Their wide outside diameter helps spread the clamping load beneath nuts, bolt heads and screw heads.
These large diameter washers are useful for timber, thin sheet materials and assemblies with oversized clearance holes. A2 stainless steel provides corrosion resistance for general engineering, maintenance and outdoor applications.

Selecting Your Washer
Choose the nominal size to match your bolt or screw. The internal diameter provides clearance around the fastener; for example, an M8 washer has a nominal 8.4mm hole. Check that sufficient space is available for the larger outside diameter.
Select the required size and pack quantity from the available options.
Please note: Dimensions are nominal DIN 9021 reference values and are subject to manufacturing tolerances. Please contact us before ordering if measurements are critical to your application.
