Metric Black Stainless Steel Extra Thick Fender Washer
Use on oversized holes to distribute the load of the fastener over a wider area.

Almost 3X as THICK as regular flat washers, extra thick washers are sometimes used as spacers. Washers also provide a smooth bearing surface against the work surface, protecting it and preventing damage.

Material: Stainless Steel 
Suitable for damp locations
Corrosion resistant

Finish: Black Oxide
Attractive matte black finish
Abrasion resistant, does not peel, chip or rub off
Reduces friction, prevents galling
Does not change the strength of the stainless steel
Practically no dimensional change to base fastener 

The black oxide coating per MIL-DTL-13924, Class 4 on 300 series corrosion resistant steel will show no signs of corrosion after 96 hours of exposure in a 5% salt spray (fog) test in accordance with ASTM B117.
